the pelcypods are small but of a mud burrowing type judging by the elongate siphonal ends of the interval casts. The gonitites may suggest normal marine salinity but this point will require further checking. The question of structural warping of the limestone in the outlier of King's Gray Limestone PG. 48 member, I believe is an illusion. I think that there were two reef heads which filled the area between them by debris from lenticular beds. The nearly flat upper surface with 2 or 3 feet or more beds extending nearby the whole length of the outlier would further suggest this. The collection of fusulines (7/3/57/10) I believe indicate slightly less turbid water (deeper?) giving these shells and smaller shell frags a chance to accumulate in well bedded strata. Pictures 4 and 5 are of the area of the smaller Gaptank anticline and the slumped #2 gray limestone. Pictures 6 and 7 are of the lower part of the western W.C. fans in the Hills proper. July 4, 1957 - Holiday in Marathon! PG. 49 7/5/57 Section 21 Section VI - about halfway between section V and IV. 1) Limestone gray, massive in 3 to 5' beds, conglomerative on the upper surface, but only slightly. Base of unit not observed. 2) Covered 6' - stream bed. 3) Limestone, yellow-brown weathering, organic frag. (crinoid fusuline) medium size quartz sand on upper surface, well rounded, but not frosted, 2', upper surface is flat. 7/5/57/1 4) Covered 16' - probably a shale interval with at least one perhaps more nodular limestone rubble beds. 5) Limestone, yellow-brown weathering, gray fresh, organic frag. (fusulines, crinoids) replacement quartz in geodes, quartzsand upper surface. The quartz sand seems to have been washed across the limestone and some quartz stuck to the limestone surface - fusulines are bedded in this ss layer. 1'. PG. 50 6) Covered 5', probably gray shale and limestone rubble. 7) Limestone, brown-gray on fresh surface, orange-brown weathering shell hash of crinoids, fusulines, bryozoans. Progressively finer grained near top. Upper surface is flat. 1'. 7/5/57/2. 8) Shale, black to blue, slightly silty, has slight fetid odor. 35', brown and variate silt zones 1" occasionally - (bentonite?). {note: illustration:
