About this map

Eagle Cap Wilderness and the surrounding Wallowa National Forest dominate this high-elevation landscape, where the headwaters of several major river systems originate. The terrain is defined by dramatic peaks such as Aneroid Mtn and Cusick Mountain, interspersed with alpine basins like McCully Basin and Big Sheep Basin. This remote area is marked by a complex network of pack trails and early mining activity, evidenced by multiple Prospects located near the head of the Middle Fork Imnaha River.

A series of high lakes, including Aneroid Lake, Jewett Lake, and Roger Lake, provide a glimpse into the glacial hydrology of the region. Distinctive landmarks such as Sentinel Peak and Petes Point overlook the transition from lush meadows like Six Mile Meadow to the rocky divide of the Imnaha Divide. This survey is particularly useful for identifying the precise locations of historical mining explorations and the primitive trail system that connected these mountain ridges during the late twentieth century.
