40 20 [Wolf Camp Hills] Section V West end of the WCHs proper - Measured N 200' from outline Below covered but wash - Uddenites zone probably. 1) LS, Conglo. w/ Crenoid + Brach frags., Conglo. cobbles 1" to 4" diam. 16', gray outcrop - top surface is near flat, has an such zone weathered brown. Many of the crenoid items are relatively unbroken and probably have had a great deal of original transport. 2) Covered, 25' - seems to be an interval of gray shale a & brown weathering calcarenite 3) Calcarenite - Brown weathering, lower surfaces appear to be disintegrated. Its upper surfaces are fairly cemented - 4" to 6" beds of SS. with interbedded silts + clays. 5' 4) Shale, blue-gray in part covered 12' 5) LS, similar to # 1 below, pebbles are ½" in diameter however; near top is a good fusulin zone - This horizon divides vertically to the west with upper part forming Kings lid "4" 16' 7/3/57/1 6) Covered, 163' - How many beds are covered here is only guesswork - The value of this interval is of comparative properties only. 7) LS, massive gray weathering, a shell hash which shows very little transportation. Coral, (long slender tetra corals), Bryozoa, isolated fusulinids, brachiopods, crenoid items. lower 18'massive - upper 5' in 6" to 1" beds. 7/3/57/3 total 23' 8) Covered, 21' - shale? 9) LS, blocky-yellow brown weathering, 6" to 1" beds, 2½ to 3'? - Can't see any shell hash. top is planar, but lacks crenellus upper 203'. Shell hash.
