Description
This report about the geography and geology of Erie County in northwestern Pennsylvania was written for the lay reader. Erie County is the only Pennsylvania county that borders the Great Lakes. It lies in the Central Lowlands and Appalachian Plateaus physiographic provinces, giving it two characteristic landforms—that of a lake plain and that of an upland plateau. The bedrock geology ranges from the Upper Devonian Northeast Shale to the Pennsylvanian Homewood Sandstone of the Pottsville Formation. The area was glaciated, and this glaciation was instrumental in the formation of Lake Erie itself. In addition to the geography and geology of the county, the text also includes major sections on the waters and the resources of the county.
