Abstract

At the time of the meeting of the Iowa Academy of Science at Drake University, Des Moines, in April, 1922, the writer accompanied by Mr. Ben Hur Wilson made a brief visit to the clay pit of the Capital City Clay Company. This pit is located along the Chicago Great Western railroad tracks south of Raccoon river in the city of Des Moines and while perhaps the most extensive, is typical of similar exposures in the city. About thirty-five to forty feet of bluish shale and a few thin beds of sandstone and sandy shale are exposed and worked for the clay used in making brick and tile and other products. One stratum fifteen or eighteen inches thick is more resistant than others in the pit and when fresh is hard and gritty. Blocks from this bed are rejected and piled up as refuse here and there in the pit. Upon exposure to the weather the blocks crumble more or less and the loose waste from them contains many well preserved fossils while others stand out in relief on the surfaces of the partly weathered blocks.
