14/2 8/24/58 Biel Berry reports that Act dol. sequence on NNE face of Diamond Mt. enters tongues and thins into shale + siliceous clasts. according to P.K.C. 8/24/58/1 - at base lower Cougls (dark brown) above highest Gaytank graze at gaytank in fault shiver at gaytank 2 bags Basil wogea of action 8/24/58/2 - Sooj. Arnold Ranch House, 2nd gully. S. crassatitosa zone (probably pretty high) Zone is about 40' thick here w/ interbedded silicstones in the clay-silty limestones 6" lick? Act gaytank there are at least 4 faults which cut the gaytank & Wogea gkds. Many these can be traced into the everly. E. The "HTC" is a Kmgan related unit of the same beds. The major fault cuts the gaytank from between the old road & the Tank south by the Allison Panel the carpholmstone an argalts - appear equivalent to the middle part of Key's 53 in the gay tank (at gaytank) The Schist. crassatitosa zone is about 182' above the base, the top there but the section is divided by several faults which may thin the section a little bit. The best silty dolomites in the "Hed" facies contain several interbedded limestone bands & numerous beds of decorated red mudstone. Dacian trochus across section here which is another question as to timing of the dacag problem are recognized. Crust. columnals, "Burgess" plates, and fragm. bryozoans (thongy?) are relatively common.
