18) a) covered 4', probably gray shale b) 4" brown weathering calcarenite and sand (quartz) c) gray shale 6' d) 2" orange-brown silty calcarenite e) 6' gray shale f) 3" bed like b. g) covered 7', gray shale probably 19) Limestone, orange-brown weathering conglomerate (limestone) in part, pebble to coarse sand in top 6", more yellow and rubbly near bottom 3'. Organic fragmental; quartz sand on upper flat surface, scattered fusulines also. PG. 54 20) Covered 10' (shale probably) 21) 4" to 8" brown(orangish) calcarenite with quartz 22) 5' covered (shale probably) 23) Limestone, calcarenite medium to fine, progressively to top. The upper 5" are well laminated, flat top, 1'. 24) a) Shale, grayish-brown 3'. b) 1" brown(reddish) calcarenite and siltstone - well laminated, very fine quartz sand also. 25) a) shale, gray 5'. b) 4" calcarenite - some quartz very fine to fine grained 26) a) Shale, gray 4.5'. b) 6"; like 25b 27) Covered - 30' probably shale and at least 2 calcarenite beds. PG. 55 28) Calcarenite, rubbly in lower 1.5', organic frags; become progressively better laminated in upper 6", flat top surface. 2', some quartz very fine sand size on top surface. 29) Covered 41', several calcarenites with gray shale probably. 30) calcarenite, organic frag. (brachs, fusulines, crinoids) 10" flat surface is not striking on this bed; wood fragments. Collection 7/5/57/16. 31) Covered 18' - probably gray shale. 32) Marl, silt and clay in matrix and as coarse sand fractions. Has a well laminated upper 2" with flat top. Sort of a transition between influence of source over environment of deposition 21'. Collection 7/5/57/17. 33) Covered 31'. 34) "Hess" Conglomerate 30'+.
