Notes on the Geology of the McCall Valley Area
Describes mainly the glacial geology of this V-shaped valley, approx. 10 km long and, 800 m wide, cut by McCall Glacier (69 20 N, 144 15 W) and Jago River valley in northern Alaska. The bedrock consists of north-dippping sediments of Upper Mississippian Lisburne limestone and the Permian Sadlerochit...
