"This bluff consists of 5 feet of red and blue shale. There is also soine conglomerate. 

 The sandstone is typical of this region. It consists of mostly white and subangular quartz, 

 but with some red' and pink grains It is frequently cross-bedded, and the cross-bedded 

 layers alternate with thin, straight layers, Iving horizontally. Some of these show extended 

 surfaces, almost perfectly plain and smooth. Some spherical concretions were noted m 

 which the grains of sand were cemented together with calcite, or with oxides of iron and 

 manganese. The thickest homogeneous or unstratified layer noted was 2 feet. Under the 

 sand in some places and interbedded wth the lower part of the sand m another place were 

 layers of conglomerate mostly less than a foot thick. This consists of lumps of limy and 

 marly materials and lumps of clay, mostly from one-half to one-third inch m diameter. The 

 shale is red, with bluish-white streaks and blotches. In one place it was cut by a vertical 

 vein of hard, red calcareous material one and one-half inches thick."
