15) Calcarenite, brown weathering, frags in lower part fine pebble to coarse sand sizes, progressively finer toward top - medium sand size at top. No apparent lamination. 3.5'. 16) Same as 14, rubble, 5.5'. 17) 3" shale break. 1.5' of calcarenite like 15. 18) Like 14, rubble, 4'. 19) Like 10, conglomerate, 1.5' but pebbles 1-1.5" diameter. PG. 60 20) Mostly covered, 7'; at least 3,4" brown weathering calcarenites, the rest is probably gray shale. 21) Like 19, conglomerate, the upper .5' is well laminated, has some black chert in seams 11 to bedding, 1.5'. 22) Calcarenites and gray shale - 3, 6" to 1' calcarenites, brown weathering. Crinoidal and fusulines fragments, 4 gray shales 1' to 1.5'. Total 11'. 23) Limestone, gray weathering, biohermal reef. 17', upper part is crudely bedded in 2' units lower part is "rubble". 24) a) 2.5' gray shale b) 0.5' calcarenite, brown weathering (like 15) 25) like 24 a) 1.5' shale b) 1' calcarenite 26) like 24 a) 6" shale b) 6" to 2" thins to east, calcarenites PG. 61 {note: illustration: bed 22: 7/6/57/6 bed 30: 7/6/57/7} 27) as 24 a) 1.5' shale b) 8" to 4" calcarenite 28) Calcarenite - lower 1' rubble as 14, but 21' as 15. calcarenite 29) as 24 a) 1.5' shale b) 2.5' calcarenite 30) as 24 a) 4' shale b) 6" calcarenite 31) as 24 a) 2' shale b) 2.5' calcarenite PG. 62 32) Shale gray, 5.5', 2 calcarenite bands, 2" to 4" thick, fine grained. 33) as 15, 2.5' calcarenite 34) a) shale gray 4" to 8" b) gray limestone, shell breccia, calcarenite 6" to 1'. 35) 6.5' - like 14 lower 5', like 15 upper 1.5'. 36) Shale gray, mostly covered [4'] <-- 14'?
