6) Shale, green to gray, 0'-2' very lenticular. 7) Limestone; dark gray, shell hash, fusulines common in thinner beds (3"-6") near base; brachs and crinoids common in upper part; 11', (8/20/57/3). PG. 53 {note: illustration: bed 1: 8/20/57/1 bed 2: 8/20/57/9 bed 5: 8/20/57/2 bed 7: 8/20/57/3 bed 9: 8/20/57/4; 8/20/57/5 bed 10: 8/20/57/6} 8) Covered, 88', probably mostly shale and thin beds of limestone in lower 10'. #9 bed has slumped down to cover this interval, variable in thickness and lithology. 9) Limestone, very light gray to nearly white; organic fragmental; many brachiopod shells and crinoid stems; some fusulines: Collection 8/20/57/4 near base; Massive beds, irregular weathering lines sub parallel to bedding 5' to 10' beds; 43'; Collection 8/20/57/5 in top bed. 10) Calcarenite, light yellowish-gray; very silty near base, becomes v.c. sand size at top; 11', cross-bedding, poorly sorted; looks like stream deposition rather than wave action. Collection 8/20/57/6. PG. 54 {note: illustration: bed 11: 8/20/57/7 bed 12: 8/20/57/8} 11) Limestone, medium gray; very fine grained, has orange-brown patches, probably local dolostone. Small crinoid stems and fusulines are about only fossils. Collection 8/20/57/7; 3" beds. 18' to top of ridge. 12) Limestone, yellowish-gray weathering; organic fragmental; brach shell, crinoids and fusulines. Total 6'; Collection 8/20/57/8; beds 8" to 1'. This bed forms dip slope to valley. 13) "Hess" "Conglomerate". See pages 124-126. PG. 55 {note: illustration followed} PG. 56 (35) Section 33, 100 yards east of prominent knob east of Brook's Ranch House: In creek bed.
