About this map

Umatilla National Forest defines the character of this 1969 survey, showing a landscape of high plateaus and deep drainage systems within the Blue Mountains. The terrain is anchored by expansive features like Thompson Flat and Buckaroo Flat, separated by the steep relief of Potamus Point. These highlands are etched by a dense network of seasonal and perennial waters, including Potamus Creek, Matlock Creek, and Thompson Creek, which culminates at Thompson Falls.
