1970 Map of Amphitheatre Mountain

About this map

The Chinese Wall stands as the defining geologic feature of this 1970s survey, marking the dramatic Continental Divide that separates the Flathead National Forest from the Lewis and Clark National Forest. This high-altitude landscape is part of the protected Bob Marshall Wilderness, where travel is limited to primitive (Pack) Trails. The map illustrates a complex drainage system where the White River and its tributaries, such as Cliff Creek, carve through the mountainous terrain below prominent heights like Amphitheatre Mountain and Sphinx Peak.
