Norumbega fault

Last updated

The Norumbega fault or the Norumbega fault system is a 20 to 25km wide [1] fault and shear zone of late Paleozoic era. It developed just inland from the Maine coast, with the geologic fault running roughly parallel to the coastline, including a portion of the northern shore of Casco Bay. [2] The Flying Point Fault in Casco Bay is considered part of the Norumbega Fault system, dividing bedrock formations that have distinct geological characteristics. [3]
