There isn't much difference between the Hess facies and these upper units this far east [west?]. King's Sect. about 2 miles east is supposed to be quite markedly different in the 2 facies of the Leonard fm, but can't say that is true here. PG. 7 {note: attached illustration of beds} [From the top of these hills one can see beds in the Leonard fm thicken and thin within short distances. The units of brown-gray dolomite limestone may change

from 120' to 0' thick in 300 yards. Thus there seem to be few "key horizons" in this interval - We have 3 or 4 chert pebble conglomerate zones near the top of the Leonard, a couple of conglomerates in the Hess facies - and that is about all. Even these are probably not of to great a regional significance as they are mostly 3 to 6" conglomerate lenses (near the top of the fm), and the ones lower are calcirudites with locally derived pebbles and cobbles of limestone. 7/10/59 18) cont. chert frag. scattered throughout upper 150'; pebble bed at 190' - 3" pebble band - ----------293'. 19) Limestone dolomite, light gray to light brown weathering, 1/16 - 1/8" laminate of limestone alternating with dolostone - 2'.

The lower part of King's section was much easier to follow than the upper part. This might be in part the result of the topography for beds 14 and higher are exposed on the top of the mountain. Here again there seems to be a change in lithology at the interval of the Hess fossil bed and just above and below - Thus, although we tried to follow the route of the measured section it is possible we missed it in the upper units. The fossil bed is a pretty poor unit here and is not the resistant cliff it is to the west. Fusulinids (often recrystallized) really make up a lot of this interval above and below the Hess fossil bed. PG. 25 7/14/59 With Cooper, Grant, Skinner and Wilde, and Stehli. Collected from Hess ranch horst and from the Word about 1 mile NW of Hill 5779 north of Leonard Mt. Word 1 limestone - 35' - 3 collections. Word first shale Collected 5-2A Word - 35' up.

grained lutites, and a few 6" limestone are rare (2 or 3) between second limestone Word and third limestone. Cooper pointed out a high Leonard limestone locality just north of the road up Gilliland Canyon at the base of the Word fm. PG. 27 It seems that Cooper's "Hess Ledge" can be traced around the end of the ridge behind the Hess ranch House and behind the horst to a point opposite the gap between the hills in the horst. He doesn't find this fauna on the front of the limestone escapement to the south (Hess escapement) because in his words "it isn't the right lithology". Thus he would rule out the idea that his fauna occurs in several horizons. Wilde is using the first Leonard limestone of King (1930) as equal to the Hess fossil bed. - This seems to solve a few problems - but I wonder how many? The section we measured in the Word seems to best fit in with King's 1930 Sect. 18, p. 71, but this on depositional strike 2.5 miles +- to the NE. PG. 28 7/15/59 [Old Word Ranch] Split Tank Collection 3-(19) from upper dolomitic limestone in Hess facies - most of this is a crinoid cochina - 15' below top. (maybe in lower limestone of Leonard). Collection 3-(2) Leonard -[3-13]. The upper beds of Leonard (2) have abundant fusulinids. Road to Red Tank Word first limestone - has limestone cobbles in the upper unit. Overlain by 15- 20' of siliceous shale followed by dolomitic #2 limestone. Collection from float near top of first limestone. Collection - 4 to 5' above Word limestone #2. PG. 29 The fourth Word limestone and the Vidrio are dolostone facies for most part here. They like the Upper 250' of Hess facies locally they have abundant relict outlines of fusulinids but we couldn't find any that were well preserved. The Split Tank Leonard section is faulted in several places and we were able to follow King's section in only a general way. Cooper said each limestone was a lense which pinches out within a short distance and each of these apparently contains a distinct brachiopod assemblage. PG. 30 7/16/59--Hess Ranch Loc. 2 Word limestone; second limestone by the road north of the horst - This is apparently second or third limestone - in the field I judged it to be the second limestone - or #1.

Dolomite - 12' to top of ridge Word first limestone - Collection 4-Word 1a, 20' below top of King's unit "a" The Word limestone contain a lot of conglomeratic stuff at this place - most pebbles and cobbles of limestone probably intraformational in part, and fine chert pebbles - Where we saw the formation, the basal limestone (#1a is very little different from #1b although King's separation isn't too bad. The distance between #1 and #2 is closer to 83' than 14' and I think these members are reversed on King's 1930 page 143. The distance between #2 and #3 is a little high - unit 6 becomes limestone and unit 5 has fossiliferous limestone tongues in it. [This area is near the Wordian shelf break and thicknesses and facies change abruptly, so if we were offset a bit from King's line of section these differences would be understandable.] PG. 48 7/21/59 Southside of Leonard Mtn. The southside of Leonard Mtn. is complicated by: a) facies change b) irregular dolomitization of beds c) several faults I have perhaps drawn the top of the Lenox Hills Fm. a little high but we'll let is stand for the moment - [Changes on] the Lenox Hills Fm is thin here as if on an eroded pre-Leonardian anticline.

The Word limestone which King maps along the west side of Gilliland Canyon is probably his third limestone, not the first one. (Collection Iron Mt. road Word Limestone A) is from this - includes a few scattered fusulinids, cephalopods and a "scachinella" brachiopod. There seems to be no need for the fault further southwest. The top of the hill we climbed is a terrva block. The Gilliland Anticline poops out to the south of this point and beds regain their 10° NW dip. PG. 52 Blank PG. 53

PG. 57 7/23/59 Morning - climbed from the "Hess" ledge up to the second Leonard limestone - made three collections based on King's Sect. 12. The base of the Capitan at Sullivan peak is a beautiful unconformity - 40' or more relief and parallel bedding. Afternoon - base of little knob of Coopers' SW end of Lenox Hills - base of hill shale and siltstone and sandstone dip 10° to the S10°W. note: illustration: Bed 1: First Ls, 35'. (3) Collection, C (Top). Bed 2: S.s., orange-brown shale-gray. 85'. Bed 3: Limestone, 3 Coll. 60', Second Leonard limestone.(Coop's Knob) This section is cut by a fault or faults and the exact relation of the knob is dubious - it is probably the second Leonard limestone, but? PG. 58 The Leonard fm in the Lenox Hills consists of series of limestone tongues which tend to become thinner to the SW and break up into a number of thin units by additional shale tongues. The structural problems are big especially in the area south of Sullivan Peak, between Dugout Mt. and the Altuda uplift. Of course, it is all covered but there is still a real problem to figure out. King's map is wonderful, but his isn't very consistent about his boundary between the Word and Capitan - his Leonard and Word also have problems - the Ammonite bed which he places in the Leonard in the west is about the right horizon for his first Word limestone in the east. i.e.,[?] It seems the Word- Leonard boundary is also inconsistent. The base of the Word in the west seems to be about the third limestone of the eastern Mts. In Section 12 this unit is greatly thickened and may represent the reef between PG. 59 the hash reef faces to the east and the basin to the west.

There isn't much difference between the three facies and three upper units here far east. King's Sect. about 2 miles east is supposed to be quite markedly different in the 2 facies of the Leonard Fm., but I can't say that is true here. from the top of these hills, one can see beds in the Leonard Fm. thicken + thin within short distances. The units of brown-gray dolomitic ls. may change from 120' to 0' thick in 300 yards. Thus there seem to be few "key horizons" in this interval - we have 3 or 4 clay pebble conglomerate zones near the top of the Leonard, a couple of conglomerates in the lower facies - and that is about all. Even there are probably not of too great a regional significance as they are mostly 3 to 6" cobbles.
