bed 12: 7/11/57/4 bed 13: 7/11/57/5 bed 15: 7/11/57/6 bed 17: 7/11/57/7 bed 18+: Lenox Hills} 17) Mostly covered, limestone rubble, purples, grays, yellow-browns - 5" to 8" beds. 28'. 7/11/57/7. 18) Calcarudite, cobbles 6" to 10" diameter; mostly limestone cobbles, but a few large chert cobbles and quartzite also. In 3' to 6' beds - cement in limestone weathers yellowish. 45' to top of ridge. PG. 92 Collection 7/11/57/8 from the zone of #8 and #9 units in section 11. The limestone have changed to calcarudites and appear much thinner. They seem to thin rather than being entirely truncated at section 13. This collection is from a saddle on the northwest side of the Ridge Section 13 is on. Collection 7/11/57/9 from Gaptank limestone, dark gray (upper most Gaptank limestone) 2 bags, one of softer interbeds, one of dark limestone. The stream gully on Brooks ranch 1 mile west of Ranch House. Remark - It certainly isn't like P. King mapped it. PG. 93 Section 31 see King's Sect 27. 7/12/57 Section 13b - Below unit 1 of Section 13, there is an exposure of gray-brown shales and orange sandstones. Whether this is a zone in the gaptank or the illusive Uddenites zone is the major concern. The field evidence to date would suggest to me it is a zone in the Gaptank - (These are vertical distances, dip 10° to the north.) 1) Limestone, dark gray, organic fragmental, mostly brachiopods and crinoids - 25'. 2) Covered 20'. 3) Limestone, yellow weathering, dark gray fresh surface, organic fragmental - see collection 7/12/57/2, 1'. 4) Covered 12'. 5) Limestone, black to dark gray, organic hash, 1.5'. 6) Covered - 28' probably mostly of #5 lithology. PG. 94 7) Sandstone, light orange-brown weathering, much quartz; cross bedding, sizes not well sorted, probably fluvitih deposition. This unit appears to be truncated to the west by unit #8. 21'; in 6" to 3' beds. 8) Limestone, dark gray, organic fragmental very uneven lower bedding plans, 3' to 5' of relief cut into truncated edges of #7. 11'.
