Geologic Map of Arigma This map of the state by Darton and others will soon be out. It is a great advance in our know- lodge. All of Arigma west and south of a line joining King Hills, Pichaco, Sacaton, Mesa, Canon, Prescott, Stradberry and Gold Basin, is as far as known all of Archeogic schist and granite, Older (Cutaneous) and younger volcanics (Pleistocene), and Bolson deposits (Pliocene but mainly Pleistocene). Associated with schists in many places in western Arigma are diomatic matters that Darton holds are Cadiniferas, because he says in one place he saw a crinoid columnal. Lawson rather thinks they are instead Archeogic strata. Again Darton says a large piece of limestone with Coral fossils that is said came from over the Colorado river in Cal. a little south west of Cibola, Arigma. As far as my paleographic maps so they lend support to the idea that all of Arigma may have been deeply covered by Carbon-Permian strata. If this is true then much of the granite I met Arigma must be Jurassic age. Such granites can be seen from western Arigma into California. The age of the matters must be determined, since it is a big factor in coming out the age of the volcanics.

Thursday, Tucson, Arizona April 2, 1925. At eleven in the morning Stroganov, Jetta and Schueber are off for a rapid trip north to the Grand Canyon of the Colorado. We have a loan of Arizona Dodge car, and Stalle along all of my passage. Had lunch and at 12.45 we are off by way of Oracle and then down into the San Pedro valley at Mammoth. Then down north the valley to (at 3.20 P.M.) Feldman and Grindelmann where the San Pedro flows into the Gila. To the south of the river are the Balliara Mts, mainly of igneous rocks and a big Pennsylvanian section - Affu Tornado. At Grindelmann we go N.E. through the gorge of the Gila that cuts through the Dripping Spring Mts. Here are wonderfully well exposed the beds of the Tornado formation of Rousonce. The structure is a syncline and an arch. About 1½ miles N.E. of Grindelmann in sandy facings of a cherty li. I collected and turned out to Stroganov Fiedelina (the Balliara fauna), Eupachyceramus plate (with much acen and high tuberculate), Spirifer grodymutana (Spiriferina - Kentuckiensis, S. spinosa (there left the first specimen), Composita satellita, Austroedia mormoni (maybe for fines plate), and Diclasma

Toridus. This fauna appears to be about 100-150 feet above the Mininiffian base at least 175 feet thin. How much thicker is not known. The fact that I got it Spirifaina spinsa leads me to think that the Monas fauna is here and especially below the strata collected in. From just over 700 feet higher we got small specimens of Fusulinia that may be F. lecalica, large Spirula coneratus (common), Springforna (C.), and Compsita suffulta. Here the list are considerably short. Probably 100 feet higher Morganas got me M. coneratus, Dalgeriana, and Steptaphendus Lillianus. Our no Orthotichia morganiana. Base was still more Penn. to the N. E. There may be 2-300 feet of Toronado here, which includes Chin.-Penn. There appears to be no Permian here.

The li. of the lower half of the Tornado are our chalky (=impure) and some of the beds are lithographic lells with a de cided emerald of pasteure. The road goes around the Ark., end of the Grand Mt, and then E. through a gap separating them from the Pinal Mts mainly of Urcheden ochers. Finally N.W. to Globe Hatch lies to the E. of the Pinal Mt's. We are stopping our night at the Dominion Hotel at Globe! Set here at 7.15 P.M.

Roosevelt Dam Friday April 3-1925 51 [3651] Left Elote at 8:15 A.M. and at 10:15 we are at Brindy Hill in Lake Roosevelt. This hill is 334 feet above the lake, with its strata dipping S.W. 20°, the strike is N. 35° W. The highest li. me of the Kinder- Devonian, with a thickness of at least 100 feet. In the upper 25 feet occur common Bellerophyllum, Meno- phyllum, Leptotrypa type, Issingtonia and Spirifer centromerus. Lee got a few other species (See p. 27). Below the Mississippian is a dolomite series that probably is Upper Devonian. Saw no fossils. Stog- amus reports Cambrian near the lake level. The Devonian is at least 225' thick. Then drove 5 miles to Roosevelt dam, and duped finally down the V-shaped gorge of Salt River to the base of the Apache Cambrian. Here the base is a coarse grained dark red granite. The upper benethaird our- surface is level and now dips like the E 20° S.E. Upon the granite lies 30 feet of canlen engl. It in a boulder bed of Proterozoic quartz gills, with an occasional jasper pebble all well rounded. Some of the boulders are 16 inches across. Coming by there are our granite pebbles.

Natural Bridge Saturday, April 4, 1925. Started at 7:45 A.M. north along the western side of Rose Creek Lake. It is a beautiful drive in and out the spurs of the Sierra conglomerate. The Paleogene series goes along the road about 2-3 miles and then comes Archingite granite. Then it is all the gray Sierra Conglomerate. North of the lake we are on the west side of the Tonto River in Tonto (Spanish for forts) Basin. Today the river has cut deeply through the Sierras and finally we go some miles through plaza deposits with much dirty gypsum. Some gypsum occurs in veins, Have pieces of both kinds. As we go on three we see elevated terraces. To the west are the high Magatzal Range of Archingite, and to the east are the low hills Sierra Ancha having Cambrian in the upper parts. North of Paeball the terraces are especially once scarred. The highest one is many hundred feet above the Tonto river and is now almost dissected. The next lower terrace dips 200-300 feet and in places is made up of 4 smaller benches. This terrace is now the cliff of two Tonto River bottom and maybe 75 to 100 feet high. These terraces go from Paeball to road to Bisola east Finally we come upon high land of lava in which the Tonto lies in a gulch. Our main road climbs Tonto Hill. Here I took 2 pictures looking S.W to Magatzal

56 At the top of the Mazatzal Range is folded and over thrustted Postergonic quartzites, see if the picture brings this out. Some miles south of Payson are are in a differnt geological and botanical world than that of Tucson. We begin to see Onesees and the bold fronts of the Plateau.

57 Oats, at Inzagatal Peak ad north to North Peak the end of Inzagatal Range. The river is across the valley with the houses of Arlantis Mine in the near foreground. Just defore are gft to the mine we see much Archeogric schist. The climb dies and across an rim ridge run Page Creek. When one gets to within two miles of Pagon me see [illegible] horizontal (Devonian) surface quartz in a fine grained maroon sandstone. From here one picks up a fine creek for 20 miles north to the great escarpment of the High Plateau. Film 1-6 is a view across to the Plateau. Had lunch at the Pagon Lodge. Pagon is granite. 4 1/2 miles out of Pagon on the road to Pine are again quartz of the horizontal maroon sandstone. The road is in the Verde River. The sandstone overlies the benched granite. I photo the contact Film 1-7 and 1-8. The section back Granite, coarse dark red. Red conglomerate of Archeogric quartz (1/4 inch) and layer grey quartz up to 1 inch.

Seven miles N.W. of Payson we saw this same serie again and in the red iron bedded sandstone separated replete with fint lime breccia, fint all are derived from the Bothriolepis. Hayden in the limatone Stigmaria first found a bed about one foot thick having an abundance of Bothriolepis whitogii animosaensis, Clithea orbicularis Schuelutella (a thick fellow), Ariculipeten, Angalina. A little farther (I think 3 miles) N.W. we saw shale lignite beds to a foot along the road. It's a shale and only impure lime rock than lode. How thick this serie is no dr not know. It is capped by a fine foot bed of white dense lie that has a lot of small hachifords that weather out silicious. The common foal is Stigmaria verrucosus (has 1 plication in series at about 3th from coal side, and is verrucose), Ps. Whitogii, Clithea reticularis, Canaristrechia, Schuelutella late peeta. Ten feet higher in another lie one to two feet thick that has lots of Pachyphyllen morrowanai (there 3 specimens), and Chalypsona. There is just a tiny 10 foot mae of Devonian.

The Min, is at least 57 feet thick. Natural Bridge - Pine Tuesday, April 5-1925. We stopped last night with the Scotch family by the name of Bondfellow. They are running a sand to raise food to take care of guests who see the Natural Bridge, a vast man of travertine that filled the gulch to a height of something like 200 feet. The stream of the gulch runs = Pine Creek through the travertine making a tunnel and hence the Natural Bridge. Frail Creek to the N. W. is also filled with travertine and it is this that gives name to the creek. We are here to see Rawsome's description of the section of Natural Bridge. The sand lies deep down in the gulch and is 700 feet beneath the road to Pine. Rawsome "Tapest" sandstone resting on the Archeogric, ganite is nothing more than the sandstone base of the Upper Permian. How thick it is we did not make out, but it appears to be like what we saw yesterday, Partally 60' thick. Above the sandstone there is about 190 feet of ag. li., dol.

64 The feldspar in this sandstone The basal conglomerate of the Portungrie has large hidden fragments up to one foot across. They are once rounded, and consist of a dense red igneous rock (=? granite) and quartzites. These must be of Archeogrian age. See Panormes's descrip- tion of it. It seems probable that the Devon sea lapped against this ridge of Portungrie land.

W Proterozie acer of Quartzites, Granite When one get outy Natural Bridge onto the Pine road we see at this lift level again the Dev. - Min section showing that that down in the gulch has been faulted down to the lower level, Faulted down 700 ft.at least. About 2 or 3 miles from Pine we examine the Dev. sandstone with thinngs of limestone (often intrafomational engl.) and sandy shale gums. Some of the lii. have angular dembs of the red Proterozie quartzite up to 10 inches acros. These lll isolated, or in small groups. Almost none like it diffused in. Near the top of the hills in sandstone we get an abundance of dark brown casts of Cetypon minornia ovis, and A. bystric occidentalis. On the other side of the road to Dr. is the highly inclined quartzite Proterozie series making a high ridge all the way down to Natural Bridge. Here the relation is not faulted. Therefore the Devonian shale lay against the quartzite ridge. In the Dev. lii. at one horizon I saw many pieces of the red Proterozie quartzite; they are of all sizes up to 6 inches across and angular. Stone not come far.

On the whole of this trip we did not again see the former gray mouth. Evidently the whole li. of the Puerco are ging into the delta deposits of the Grand Canyon = the red Supai.

One and me- half mile fm Pine we came upon the Lown Pennsylvanian li. Here they overth into much chert, and in thin chert are pit a stundane of Spirifer prolgymentana, I. carneatus, Composita suttrilita (large), Clithyridina, Reticularia, Chibi- dmella peersi, Derby nstructa, Productus semi- reticulata Hliverianon, P. nebrascensi, Articuloida Chneta mae-stirus, C. mist sinus, Midelinia, and Zophothllum prolifurme. How thick thin Pennsylvanian limestone is are do not know. We saw at least so fut of it, and all creathes out much red chert. The forins are the redder face. Thin li. lie beneath the whole of the Lupai. It in therefore if early Penn. age, but not or early as that are our over Biscilomus which suggested Manor fauna. Staying one night at Pine. At the Drulburg Inn, a sort of camp run by a Mrsmm (M. F. C. Fuller).

68 This occurrence is somewhere between 1000 and 1600 fvt. hgt. see centry p. 69. He saw the calcareous gray sandstone in the gulch beside the road to Stranberg, near the fork in the road to Flagstaff, This limestone may underlie the Supai, and maybe included by geologists in the Miss. because of the limestone nature. see p. 34. This refers to Hermit shale in the Grand Canyon.

Pine - Jerome, Ariz., April 6, 1920 Started away from the "Mulberry Inn" at 8 A.M. in a chilly cloudy morning. Pine is at 5600 foot above the sea in front of Plateau escarpment. On the great cliffs one can readily see the red Dupai dolmo, and near the middle a peg band, and down up some red beds but mostly beds of something smally the upper fold escarpment. Leaving Pine after not one-half mile, one begins to as- cend the escarpment, and often one get on the Flagstaff road one see that it is cut into the Cremonia sandstones. The top of the Plateau is about 7200 foot, so there is 1600 foot to be accounted for. The lower red Dupai is exposed all about the level of Pine and it goes up to at least to the grey band that may be 50 to 65 foot thick. I judge this to be near the middle of the 1600 foot to be accounted for. Apparently this is the "compact fragli, with floriflora camera- tuo" of the Canyon Creek section described in page 35. If this is correct then the Lower Dupai is at least 565 feet thick. I do not know if this takes in the lower limestone collected in Saturday last of Pine, and that was the floriflora molyntanae - D. camarius fauna. The Upper Dupai one did not make out, but seemingly it is present above the grey band, and if so it is far more a sand- stone series with then beds of shale. I estimate this gone

70

as daring about a thickness of 300 feet, it may of course be less in some; other data given it is a guess. Then comes the Coconino sandstone, a yellowish- white fine grained sandstone. It is all exceedingly corn bedded with occasional beds rippled. The lower two- thirds is true corn bedded, the presenting being in various directions. The upper third has large zones of presetting that run more general are southward or southeastward. How thick it is one did not stop to estimate, but at Canyon Creek it is 535 feet thick. It is probably as thick here. We saw our fossils from the can see any indication that such might occur. Yet the road cutting is so new and fresh due that some repair may come to study it. Finally when one gets on the top of the Plateau one are in the lower beds of the Kaibat imprecise direction. This is at about 7000 feet, then one saw a road sign saying the level was 7253 feet, also in the Kaibat with much more above. Therefore the Kaibat is at least 400 feet thick and may be as thick as in the Grand Canyon where it is 400 to 600 feet depending on the amount of erosion. We saw all this on the top of Strawberry Mountain, and collected a lot of fossils are along side of the road about six miles out from Pine in the File of staff road. These come from the lower part.

72

of the Kaitat, Later on are seen the fossil beds and at their contact with the Creonior the li is recline with the Produeti. The fauna appears to be common to the entire Kaitat but far more common below than above. The Kaitat is an arenaceous limestone, in which the exceedingly fine sand makes up the greater amount. It is thick bedded and on Kale grey, and if a yellowish-white. Ita in first practice, but only white on larded surfaces. The forms as a rule are siliceous and the formation abounds in emetic may flints, they occur out singly or in beds, and the emetic is more common upwards. The Kaitat fauna is essentially one of large Products are few of which have pronounced central Sinuses. Piriisi is the largest and most common one. Then occurs rarely Chickelleri, the four species described by Dentury. A sponge is very common. There is also a small glabrose Com- posita. Archaeocidarina spines and plates are also often seen; the of this are of minute. There is a very large Aric- culoseptem, and Helicer described by Dentury. I saw one or other kind of forms. The highest Kaitat seen is a dark arenaceous li derived of forms, and abounds in small diagenetic cavities, filled with iron pyrite. On the Kaitat comes the common vesicular late

Congo area films. It filmed on a very rough topography. The Flopstaff road keeps on going through the pine forest, and in our road at all but a jamette somewhere on the ground winding in and out between the two. On one of the branches of Clear Creek we had a fine opportunity to see the contact of the Kaitai in the Coconino. It's as sharp a contact as can be and without the slightest transition. The Coconino sandstone is more decidedly pre-Settle and sharply upon rests the Kaitai areaceous limestone. It's at once full of products. Took a picture of the contact. It was from 2 log drive on dry pine roads through two fires to Long Valley, where we bought some canned goods for lunch. At 3 P.M. we start again for Jerome. Finally at 13 miles east of Long Valley we fell into a mud hole. This was about Hocksett and it was not until 7 P.M. that we got out of it. It was then about 20 miles to Jerome, where we arrived at 12:30 A.M. Left a room at the Jerome Hotel, but Stjarnan and brother after four attempts finally found some cots at 2 A.M. So just in time y'allers, parked on the side of a very steep mountain.

76 Directly east from the roof the lower third is the brilliantly red Supai. Then it is all light gullmint all the way up to the TIP of Mogollon Plateau. Of this 1/3 by far the greater half is of the Coconino and what there may be of the Supai. There is a hack line (may be a spurt with tints) and all above it is lightly tinted. On top of the Plateau is the oxide spread lava and here and there are volcanic mass. In the north is Bill Williams and another mass immediately south. Then the grand San Francisco Drift that are snow covered. Directly east of the hotel is a long many flat-topped mass. South east begin to appear the high parts of the faulted zone and in the far south east are the tips of Decora Apache and Mogot gold with the Tonto Boam and Roosevelt Lake in between. The "Rim" and outlying parts go five north to south about 1/3 the mile. The red Supai has clearly an offset bench, separating a lower mass from an upper one. But both are equally red. The upper mass is about 1/3 and the lower 2/3 of the white red streak.

Jerome, Arizona, Tuesday April 7-1925 left up late, and rested all morning at the hotel writing of the previous days work. From the roof of Hotel Jerome one gets a confused view of the country to the east and northeast. In the distance the high in the lower half (north) & lower third (east). rims conspicuous red cliffs on the Lubar, above the edge of the Plateau stones the high snow crowned San Francisco volcanoes are farther to the west the lower Bill Williams Rt. Below the rim and much nearer Jerome, both on the east and west side of the Verde River are the Tertiary "lake beds", rather large depressions having gypsum. Back of Jerome, to the west, Black Hills is capped with Paleogene limestones (Clw. and Min.), terraced which in the "Tapeats sometime". It rests on the Archeozoic schists and dolerite. Just east of Jerome are the Paleogene limestones dropped 1300 feet, or the Black Hills are raised that amount. See the 12 postals and pictures purchased of the Highgrade Art Studio of the scenery about Jerome.

Jerome, Wednesday April 8, 1925 Started away at 7.45 A.M., out on the Prescott road about 3 miles from a place known as Walnut Spring. This is an abandoned mine building. He climbed about 120 feet did one Archeoptere (Archaeopteryx) oolith. Then came the so called "Tapeats Sandstone" which is not Cambrian but the underlying base of the Upper Devonian. It is at first an arkose erylomite, rusty red in color, much cross bedded, with the pebbles on a rule between 1/4 and 1/2 inch, with some 1 inch long. All the pebbles are outsrounded or angular showing but little transportation. Feldspar pebbles are Com- mon. There is some thing like to foot of this. Then the sandstone becomes finer and gradually changes into laminated dense dark colored limestone that has diagenetic alteration in small cavities, filled with calcite. You may be so lucky this. These laminated beds fans into a series, first of almost white crudely fracturing li., then pinkish and dark dove colored very finely crystalline dol- omite that are interbedded with at least fragments of thick calcareous (or 3 or gypsum) shale. These go on about 330 feet, and some have recognizable trails although we does facial like markings that may be altered organisms.

80 Ransome says Himipta crota occurs here, and we may have seen it in small single valves.

meeting into little chips Then the dolomites become more thick-bedded, with often goes in between. These have a thickness of about 150 ft. In the base of this series appear the first recognizable fossils: Cystia cystiniformis, a small spirifer related to I. oarnacensis, small cup corals, and numerous a prostrate Agryphora. About 20-ft below the dolomites have some fossils and partly silicified. Here the ends predominate many cup corals, Eridiphyllum, Acervularia david- sni, Camarotrochia near saphir, hospidula ornis (no one specimen was seen). About ten-foot higher there is a ft bed filled with a branching Favosites. Then a bed of Acervularia, alternating with Favosites. In this way the fossils, all siliceous, appear in rows to the top. But it is not easy to make a good collection. The Agryphora is the commonest good fossil. This ends the Oerminian including the basal crag and sandstone about 580 ft thick, Resedae. The Mississippian lie in sharp contact upon the dark dolomites of the Oerminian. It is a dis- onformable contact. The whole Miss. is given a thickness of 250 ft, and this appears to be correct. It is a thick bedded series gray-white limestone

82 These appear like of the group of P. semireticulatus.

83 almost wholly made up of crinoidal matter. The brachia are seen, and even columns too numerous to count are rare. Towards the top the crinoidal matter is less and finally almost disappears on day the li. look like those of the St. Louis formation, at St. Louis mo. Near the base of the Miss. Li. Strongman got a large dorsal valve of a springothyrus that reminded of S. typus. Branchyllum goes throughout the entire thickness. Some Springonas were also seen. Near the center a species Spirifer reminding of S. plicensis. At not 70 feet beneath the top in red shales are got different layers than a different springona and Lithostrotion proliferum. Finally at the top we saw Branchyllum, and a large cup coral. Bolter last summer got here some large Productus that Strongman noticed. For other forms see p. 37. The top of the Mississippian is eroded very irregularly and in one place we saw a knifed cutout to put right sticking into the Dupai. The contact I sketched is about as follows: Dupai Mississippian

84

85 In the hills near Walnut Springs the Dupai has a thick limestone cap over 300 feet, and is there crowded with the resicular lara. In general the Dupai is bright red here, the deepest red being in the sandy hard shales or rather the muddy red sandstones. Those masses of the greater part of the mass and are intertwined with thin red sandstone patches of occasional one or more feet thick. There are also areas across limestone but according to Bettes who examined them last summer, there are no fossils present, at least no large ones. Accordingly the living frutiforms along Penn. ear near Pine is not developed in the same manner. We then tried to get to Iscamne Creek to see the Dupai, but failed to find the trail after driving at least 10 miles. On this trip we saw much of the Lake Beds that are supposed to have been formed in lakes dammed by the resicular larae that flowed over all of the higher ground and in those cases across a part of the lowest part of the Neele River Valley. Therefore the age of these lake beds are of the time of the larae act later; they must be very young, and yet they are now deeply dissected by erosion.

86 These empls are largely informational, but since hands have come in quantity and so on it is plain that outside material is also coming in.

Jerome - Flagstaff, Thursday April 9, 1905 Got up at 6 AM, to get an early start for Flagstaff, hut after all it was 9 before everything was in order to go. It was just 1000 feet down here not miles and then by Cottonwood and easy across the Verde River and the Lake Bolo. Ahead one mile of the Rim. At 23 miles early Jerome we began to get in the first Dupai. This was in the lower part but out at the base. Forice I saw goes 3 to 5 feet thick of an impure limestone con- glomerate, mostly of the Dupai but to our surprise there was also an occasional piece of the Garapi schist. The pebbles are fairly well rounded, most often flat and found together by a calcareous cement. Have a piece of it. Later on I saw other interlaminated conglomerates, but cannot them. Probably these congls. goes are more common than appeared to me. The whole Dupai is said to be wood there. The muddy phase of the Dupai predominates and it in the deep red color of most of the Dupai. At times the muddy zones are decidedly more redded, but as a rule these strata show little of it. Rippling is rare and often present in any restricted in area and of the type made in shallow water. When clean sands occur there are pink in color and decidedly earth red. Dust goes are not common in the lower part but and which from 3 to 6 feet thick, begin the ones or above the middle and especially in the

88 Shortly after leaving Redmon I saw in the forest such other thick tree about 100 foot of Mississippi it was in even contact with the Tupai. It was too far away to walk to in one limited time.

"Here they range in depth from 3 to 10 feet. Upon 3,000 ft. In the lower half there are irregular thin bands of a greenish color, sometimes nodular and then con- tinuous and in thickness from 1/4 mile up several miles in depth. It seemed to me these are caliche deposits. When one gets to Ledoma we found the formations to be more beautiful amphitheater of Lupai temple pillars and jagged spurs. Near all of these are of the Lupai and it is not as one gets nearer the Rim that the Cocoonine and the Raitat are pre- sent. This place ought to make a good tourist place. Ledoma from Oak Creek about 33 miles from Jerome or 37 miles from Flagstaff. Most of my films 3, 4 and 5 (1-2) are of this Ledoma area. The Lower Lupai appears to be unbroken in the Upper Lupai (about 3,000 ft), which is tan and because it has for some finding to pull out white sandstone from 3 to 10 feet thick. Many all of these are decidedly corroded. Then the Upper Lupai appears to form broken into the thick Cocoonine (3,700 ft thick), and below it is corroded but soon goes into the dry foresetting or well seen in the Grand Canyon. Most of the sand grains are somewhat rounded and the cavern bands are of well rounded sand like the Tor Speciman itself. It was not well enough exposed to look for any phidion tracks. The foresetting

90 Today's long distance geology did not reveal a break in the Supai, but there is probably one here as in the Grand Canyon. Stegmair examined me of the firm-bedded pink sand- stones and found it surrounded on all four sides by the Supai. This looks to me like a channel deposit in the Supai, fine sands laid down by wave action in the previously made channels. When we go up the Plateau we had a fine view of the San Francisco Out, I photo them.

91 mass of [illegible] turner in to the west and south-west. In long descent th[rou]gh them- To see the Papai and Coconino are the deposits of a delta with the material coming out of a desert. The delta is growing to the south into deep and massive water. We had found marine Penn, at Pine and faith, South the whole of these strata are marine and morp[hy]li. The land was to the north and northeast, and the material is detritus of dry mines since the material is very fine and [illegible] sorted by wave action. But occasionally and locally are the sands well sorted. As the rivers meander over the delta they tore up the old consolidated material and made the local cycl[es]. The road from Sedona to the top of the rim is a very steep one and the last 2 or 3 miles take all the brim. The bridge can has, finds also go up, but old men have a very hard time of it. Once on the Plateau it is all things for pine, fir, oak and lark trees. About 8 miles from Flagstaff we again see the white chert magnesian Kaibab. The timbers are now high in the Kaibab and nearly one of the forms are small Tulares, Pleurophorus, Argalina, Edmmelia, and Babelia. Also saw a large Nautilus frag chambr

An occasional large Production occurs, but someone Piresi. We are staying at Hotel Weatherford, run by Mrs L R Hall, Flagstaff, Arizona. Flagstaff - Grand Canyon Friday April 10-19 '25. Shipped a small box of films to sale. Paid $4.00 in 30 pounds. Then asked for my field glasses, sent to Santa Fe they had not come. As I still have to go without them. Left my New Haven address with the clerk and a full God to have them returned in case they come to Flagstaff. At 9.10 - are start for the Grand Canyon via Chino. It's about 70 miles. Thinking the old Grand View Hotel was still going our first attempt to it, my to find it a hundred day ago. Some Surveys of the U.S. Agri, dep were living in it.

Congric Loras. Near Flagstaff stand the high San Francisco Mt an ancient Volcano. They are now that around with snow. We drove to the south of them and then to the east of them. All about are volcanic cranes, some high, but none as high as the San Fr. Mts. All about Flagstaff the fresh is being cut off, and many to the south of the Santa Fe R.R. Farms are like seen in many places about Flag staff. About 25 miles north (Maine the volcanic cones and flows chips out. Those are cinder cones, the Lopilli being up to near 1/2 mil high; we are angular vesicular lying in a cement of sand. They are dark darker than floors that look as recent as if made of a few years ago. Between the volcanic piles there are smaller hills, but none are the striking features of southern Arizona. About 18 miles pm Grand Canyon we saw a high and striking red butte on off the road. It is known as Red Buttes, and to my surprise it is a Triassic buttle capped by the younger lara. The section is about as follows: Lora at top pm 100 to 200 feet in mine

The lava at the top lies flat and is of considerable thickness. It belongs to the young Tertiary flows, as it is on the top of this erosion remnant it must once have extended much further than now. The amount of erosion takes place since then that these flows are not or recent as is often believed.

Skimarems bright red sandstone that is also slightly conglomeratic. Has red calc edony or silicified coral. Estimated thickness seen on northern slope to be at least 75 feet. See the two samples.

Saw nothing in the solid test of an organic nature. About one mile north of Red Butte appeared the Aspen habitat. Examined it at several places, and always saw birchle, Schizopodes, Pleuro- thonus and other forms. It is a whitish dry fine grained mixture distinct that occurs out in places much chest.

Grand Canyon, Saturday April 11, 1925 Got up at 6 and had breakfast at 6.30 A.M. We started down the Bright Angel Trail at 7:10 and at 10:15 we are on the Tonto Platform. I went to 1 mile beyond the Indian Gardens, or from miles down, and it is still 3 miles come to the Colorado River. At the four mile sign we failed, Strong and Dobson going into the river. After taking a number of photos I only curled myself back to the top of the Rim and for to the hotel at 4 P.M. Theope I walked our 8 miles and climbed 3500 feet. And start for a man nearly 67 years old. I am not very tired out, but could step thousands. The contact of the Kaibat-Coconino is a sharp one, therefore that is here a break as we saw far to the South. I saw again the three joints in the Hermit shale guttling the Coconino, and now filled with Coconino sand. Patroled the place again. Can these joints be due to perculating under ground water? The contact of the Coconino and Hermit is as sharp as can be. Both phenomena lend support to the idea that there is a break in deposition here. Near Redmore than was our evidence for break. The contact of the Muwar and Redwall is also a sharp. Patroled the contact. The Redwall fracting vertically while the Muar matters in clear bedding.

Then a shaly zone for 70 feet. Upper Lufai is decidedly thick bedded sandstone for about 330 feet = Hermit. All of the thick bedded sandstone tends to be more lens cus- bbed.

The Government (Nat. Park Dep.) is building a new trail down into the Canyon early Jaki Point or at Jaki Point. By next year this new trail should be open.

Grand Canyon, Sunday April 12 1925 Started at 7:30 A.M. east to see the Canyon from all the river points. First at Yaki Point and made 2 photos. Then to Thor's Hammer and made 2 photos here. Toledo Grand View Point 12 miles north of El Tovar. Made photos 5-9. This place looked better in the morn- ing light than often we first saw it late in the after- noon some days ago, or Varajr Point Then to Desert View which is 32 miles east of El Tovar. This is by far the grandest and finest view of the Canyon, and rich in color since so much of the red Chuar (Pterozoic) is exposed. Here the Plateau slopes the Kayt at surface to a considerable lower altitude. The easternward slope of the white series is in harmony with the earlier slope of the Grand Canyon Mts. From Varajr Point one has a very extensive view to the N.-E. and E across the "Painted Desert." First comes the gorge of the Little Colorado river that joins the Colorado River at the end of the Battle Canyon. At this junction begins the Grand Canyon. Beyond the river is a range of cliffs that maybe the Vermillion Cliffs and about 10 miles from Varajr Point on the White Cliffs. Far to the N.-E. stands a dark hill Mt.

remnant of the Titanic. He tried to reach it, but eventually found out that one had to go about 30 miles around to the south to get to it finally in the north. Took 8 photos in the morning and late afternoon at Navajo Point. Finally visited on the return trip Pinal Point which is not far to the S-W of Navajo Point. Grand Canyon, Monday April 13-1925 Started away at 7.30 A.M. fn Bass Ranch, 25- miles to the north or down the Colorado River. This place ones closed and no one had been over the "dirt road" for months. The roads are all washed out and we had a hard time getting over them. At different times we thought we were going crazy and came near firing up. Finally at 12 o'clock we arrived at Bass' Camp. As we could not put in more than three hours I con- cluded to head for Kaibab trails about one-half mile to the S-E of the Camps on the easting out of the dell. Trails were good and traveled there. Stozanne intended to go to Fossil Mt., but finally

106

107 concluded it would take all his time to get there. He therefore devoted the next hike to M.E., and got about the same things I did. He found the return trip easier than the going and got back to the hotel at 5 P.M. Grand Canyon, Tuesday April 14-1920 Left at 7.30 m m in car for the Hermit Trail. At 8.15 are once at the head of the trail where we left the car. For the three yrs walked down to Red Tops at the base of Hermit shale, Sturgess and Doctor then went on down to the camp to stay over night and walk out to morning. I had to get back to the head of the trail by 3 P.M. since that was my last time to get a bus trail to the hotel. Got back at 3.45 p. M. The Kaibab - Coconino contact is here a sharp one. Below is the yellowish-white orm-beded Coconino sandstone, and the Kaibab has a sandy base 6 to 10 inches thick, followed by a soft sandy dolomite 12 to 18 inches thick. Then the regulation thick-bedded Kaibat dolomite. There are very hard and then soft gums

The Coconino is extraordinarily forest here, and at times is decidedly crum bled. It is in the lower third where the Styrcehalian tracks seem. And they have exposed by areas of the sandstone on them and made a stone steps beside small to traverse them. One series of tracks is continuous that leads with foot. Large good specimen. I did not see -- none as good as the one must at Yale. It is at this place that Daile quarried out the lot he sold to the University of Arizona. The Coconino - Hermit is a sharp con- tact. The former is a yellowish white fresh sandstone resting upon a deep red sandy - muddy shale. From the trail one could see about 10 sandstone dikes like those of the South Angel Trail. The Hermit - Supai contact where a markedly eroded me. The thinly-beded sandstone of the Supai are deeply pitted -- as deep as Sufut- and it is at Red Top in me I there that the Permin plants and styrcehalian tracks come from.

Grand Canyon, Wednesday April 15-1925. I spent two hours sitting and walking at Powell's Memorial. It is built of Kaitab dolomite resting on the "Lignite" Linestone" at the outer end of the Point east. It is in the style of an Aztec Sacrificial Altar on the top of which is the pedestal of ordinary cement dating from the southern explorers the large tablet denoting mpl. 110. There are three thin holes for tablets but none were put in them. The whole affair is too cheap looking to commiserate or it is a reflection of what Canyon thinks of this great gift, under such a crown and or daring a slight application. The pedestal should be of some enduring stone with either this one tablet or 2 or 3 at Tablets. Then around the lower part of the Kaitab monument should be built the geological columns of the Grand Canyon are about in the style of the Canyon. All of the creatures of the canyon. The view from Hpi Point has a ridge oncep both up and down the canyon than at Bright Angel or El Tovar. The elevation here is also 7050 feet. There is a good foot-path all along the rim from the hotels to Hpi Point. A walk along this part of the rim furnishes a fine illustration of the Canyon. In the afternoon I sat on the benches in front of El Tovar Hotel and studied over the topography and geology of the scenery of the North Rim on either side of Bright

Angell creek. Made notes elsewhere. Then cracked along the foot path northeast to Jarafai Point that is also known as Grandeur Point. Here again is a wonderful snap of scenery on either side of Bright Angell Creek. Off to the west is an opacious Trinity Creek. I must return to this place to morning morning to do photography. When Jeff Travel to the Hotel Sturgeon had returned from Hermit Camp, he had little to say, altogether too little to be satisfactory. As for Belter he is as gloomy and selder as a pop. It is a waste of effort to help this funny man. I complained of him to Sturgeon, and was greatly surprised yesterday to see him go down the Her- mits trail without a hammer. When one stopped to look at things Belter sat down and held his head. Too tired to be interested, and fat he is getting fat on the trip.

114

Grand Canyon, Thursday, April 16, 1925- Stofanm went to Bas Camp today to find his clinometer, but another car had been there yester- day and probably took it away. He then spent the day collecting and got a fine lot of Kaibab pine. He says birds begin to appear 140 feet above the Coconino. The Bass' trail goes to the foot of Fred Mountain. I started the morning sketching on Herdman Point and then walked another mile or so still further east. At Lunch I again met the Swedish artist Mr. Frid Fors and pointed out to him the features and my ideas of the colors and structure that an artist should put into his pictures. He uses a lot of too much blue in the distance. All afternoon I looked for blue, but saw none ex- cepting slate in the afternoon in the darkest sha- dows. Here it is a Blue Haell and no other colors strike through it as Frid Fors paints. He works in open- class.

116

Grand Canyon, Friday, April 17-1925 Spent a part of the morning walking over 2 miles to Hopi Point, where I again took 3 photos. In an hour watched Artist Grid form of Stockholm, Sweden painting two temples to the north of Bright Angel Creek. His work appears to me somewhat sketchy and uses too much blue. He tells me that he is using far less blue than ever before. During 1924 he painted here for 8 months. I judge he does about 2 or 3 pictures as a well and wants from $50 to $200 dollars a piece. Then returned to my room and packed the tree of prints. Shipped by Parcel Post weighed #3.460 charges. At 7.30 A.M. saw Stoganner and Delber M. They go via Williams, Prescott, Phoenix and Tucson. Will get home sometime Sunday. It is a cold windy day. Bilmes day of anyodther track last winter on the Hermit trail. At the National Park Office I was told that 9 kinds of tracks occur here, and that they are known almost everywhere where the Cocos-nutr sandstone is well exposed. They have one example at the office building. Mr. Aiken is here.

Grand Canyon, Saturday April 18-1925 Cold windy night. At 8 A.M. I start east on the rim trail to Grand Point and to E. of Yarapecsi Point. It is all getting very familiar scenery, and I am on little that is new. But the views are as fascinating as ever. The foot of the Plateau comes down as far as the base of the Hermit shale, but here it is much dreadful. And yet ceases with the base of the Kaibab. The Coconino is nearly always a vertical cliff. At 3.45 I took a walk W to Hopi Point to see the last of the Grand Canyon. Got back at 5.30. Called at El Tovar to see if there's any mail and just then Mrs. Mulford came up to me and said that she ad her son John had just ar- rived by auto from Williams. I am sorry they did not come earlier. It is now too late for me to stay long since I have my railway tickets. All arranged and booked. At 7.35 I am off in a sleeper that goes through to Chicago, will be with me in New York Wed- nednesday night.

En Route, Sunday April 19, 1932 The Hupin train got to Williams last night at 10, and remained here until after this morning. Then it started east on the California Limited. It was ready for breakfast by the time we got to Flagstaff. This was 6.45 A.M. East of Flagstaff we are in the Painted Desert of Arizona area. Adman— the entrance to Petrified Forest is in a sort joshua desert of dark and drifting sand. Last goes much of the morning. Everyone and then we see mesas and suddenly we are rising into canyon rocks. A little after noon we are still in undulating but more rocky, Cretaceous age, and coral mines. We are now in New Mexico. Shortly afterwards we begin to see lava flows, and on the north side of the railway is a narrow tongue some hundreds of yards that extends about 10 miles. It finally ends into this dark extension. In places the crust has broken down and moved by the fluid lava beneath. Flow structure is very common. It all looks so recent, and is almost without vegetation that one thinks of it as having formed within the last two or three years. To the east of this place frequent storms we see these lava flows but are look so recent. These are fissure flows.

122

Even until night all is desert looking. At 5.10 P.M., we are at Albuquerque, and for 40 minutes we stop here. Everyone is out on the low platform or in Fred Wares's wagon cleaning at the Thmps of the Indians. He has lotsy polished front arrow from the petrified forest. Also some Canyon Diablo meteorites. There is a flat sandy sign at Albuquerque and for several miles south of the place are for ten miles north how are irrigated farms They finally end in Indian farms. Most of them appear to be for alfalfa for horses and cattle to provide more food for the range cattle.

125 On Route, Monday April 20, 1920 When I got up this morning we were part of La Junta, Colorado, and what a great change has taken place since last night. The land is range country with lots of cattle everywhere. Then one gets into Kansas the land is green and gets greener, farms become plentiful, and by 10 A.M. are in the land I smell and honey. It is all plain country, almost flat and without fruit. By noon small local forests appear. Don't see all day east through Kansas. We got to Kansas City at 10 P.M. Yesterday and today in the afternoon the temperature is warm. The natives are around in shirts without vests or coats. Damfully just as I ask fear when I got into the plains country, hot and sweaty. I am taking a little 1 quinine to prevent any taking cold. Went to bed after getting to Kansas City, Mo. This was at 10 P.M.

In the minutest room the cases on the end have a mahogany wall on which is printed a long general label in gold letters. It looks good but must be expensive. For reading purposes it can be done better in paper. I did not see more than 10 people in the museum. Not at all like New York.
