A - flat bedded ribbon - banded bitum. ls.
B - Coarse calcarenite to rudite with R. hessensis & Spiridiophora fusulines at base
C - Thin - bedded somewhat siliceous shaly ls, yellow weathering
D - Massive calcarenite - biohermal with Spyridiophora
Sullivan Peak Equivalent
On top of A are steeply dipping yellow weathering siliceous ls. very thin bedded 1/4 - 1/2". Occasional thin lenses of calcarenite & shell debris. One thick band 2 - 3' below yellow beds, perhaps 10' - 15!
Lowest beds of B are coarse calcarenite with spy. brownish gray, some silicified bryozoan & "algal" material
Massive biohermal beds 3' - 4' thick.
