bed 3: 7/5/57/1 bed 7: 7/5/57/2 bed 8: 7/5/57/3; 7/5/57/4; 7/5/57/5} PG. 51 9) Covered, 53'. 10) Limestone, yellow-brown weathering, (gray fresh) organic frag. (crinoid) - I'm not sure this unit is not slumped down from above. 3'. 11) Covered, probably shale in great part. A lot of limestone rubble in upper part - 37'. 12) Calcarenite, brown-yellow weathering; some sand (quartz) and upper surface loaded with fusulines, but seem restricted to upper 1". 2.5'. 13) Limestone, rubble for most part, pretty badly covered and it is possible that there are several shale intervals. 26'. 14) Limestone, a) Calcarenite, brown-yellow weathering; medium sand size through out 2.5 to 3.5 feet; flat top. b) shale parting 2" to 3", gray shale c) Limestone, conglomerate at base grading up to coarse sand sizes, organic frag. Crinoids, brachiopods, corals, bryozoans, 5.5'. PG. 52 {note: illustration: bed 16: 7/5/57/9 bed 18: 7/5/57/10 bed 19: 7/5/57/11 bed 22: 7/5/57/12 bed 25: 7/5/57/13 bed 26: 7/9/57/3 bed 27: 7/5/57/14 bed 28: 7/5/57/15 bed 13: 7/5/57/6 bed 14: 7/5/57/7 bed 15: 7/5/57/8; 9/27/57/3} PG. 53 15) Biohermal nodule - lower few inches maybe shaly and then rubbly limestone, great part is limestone, gray, (weathering - yellow-buff). Corals, brachs, sponges(?), fusulines. 10'. 16) Covered 14' on dip slope of 15+14. 14 (10/99 this seems = 12' to thin). 17) Limestone, fine pebble conglomerate, organic frag. of which fusulines seem to dominate, bryozoan 3', finer grained near top, flat upper surface.
