24 2) 34' covered - probably a gray shale. 3) LS, brown weathering, gray on fresh surface. There is a organic fragment of rock - by brachiopod and a few coral frags. The lower bedding surface, this units contained pockets of Jurinence Collection 6/28/57/2 31" 4) Covered internal - 23' 5) LS, yellow brown weathering, on beds 4' to 8", Crinoidal + jurinlime serlina lines, 50' to the west the unit became massive and compsed only of crinoidal fragments. Collection 6/28/57/3 is from base of this unit. Collects 6/28/57/4 taken 20' above base of this unit. The upper part of this unit became massive and is probably a bioherm. It trails off in both E+W direction into thin beds at the top of the western bioharm and thin beds at the base of the eastern bioharm, 33' 6) Covered - 8" probably gray shale - Thickness to 12" but this depends whether it is between bioherms or at the top of one. 25 7) LS, gray weathering, I take this to be the casey P. Kings # 215 This is a fine grained calacrite at this point. The 2 foot gravelly material below the base of the unit has a jurinlme fauna (Collection 6/28/57/5) 4" thickness of unit - eroded surface - 33' 23' 31' 34'
