Reconnaissance bedrock geology of the Wabassus Lake quadrangle, Washington County, Maine Reconnaissance bedrock geology of the Wabassus Lake quadrangle, Washington County, Maine

Generally, shear zones in quadrangles of this area parallel the faults, especially those trending northeasterly. Additional faults and shear zones doubtless present in Wabassus Lake quadrangle but not shown for lack of field work in some areas, and lack of outcrops in others. Some lineaments seen on areal photographs, but not field checked, might be faults.
