Abstract

Feulner, while mapping the bedrock of Clayton county during the summer of 1951, observed numerous large chert erratics scattered over the landscape west of Strawberry Point. These erratics lie near the edge of the Iowan drift plain just south of the northfacing Niagaran escarpment, which is formed by the erosion of Silurian rocks.
