Abstract:

Most of the rocks within the Study Area are of Precambrian Age more than 600 million years old. Since at least the mid-Paleozoic time, the area has been tectonically stable. Hard bare rock is exposed at the surface in relatively small areas, but a soil and glacial mantle ranging from a few to a few hundred feet thick overlies the bedrock throughout most of the area. A Bedrock Geologic Data Map has been compiled which gives the areal distribution of bedrock in the Study Area. Author
