The 5 2/3 biohemg Ring has beds dipping near east at this point and many blocks of this ls have slipped down to cover the contact. This Uddentus bed is high in the zone and as a gray nodular ls with included brown crust weathering sietstones. The calcite in the original rock has been recrystallized, probably as a result of the heat deposition. (15) flexure at this end of the hills, lowering the eastern end. 6/26/57/8 - Collection from brown weathering brachiosped and juvenile cochinea ls, about 25 feet stratigraphically below 6/26/57/7. 6/26/57/7 10' Shale? gray Brown ironstone 2 1/2 ' 15' 6/26/57/8 Shale gray 3' The east of the hills are going to present problems in covered cuturals and erratic discontinuous deposition.
