About this map

Sacajawea Peak and the Matterhorn dominate this 1990 survey of the high-altitude landscape where the Wallowa National Forest and Whitman National Forest meet. The terrain is defined by dramatic ridgelines including the Hurricane Divide and Hurwal Divide, which separate deep glacial valleys and alpine basins. The central Lake Basin is densely concentrated with water bodies such as Mirror Lake, Moccasin Lake, and Douglas Lake.

The presence of numerous high mountain passes, including Horton Pass, Glacier Pass, and Hawkins Pass, indicates a network of traditional travel routes through the Eagle Cap Wilderness that predates modern infrastructure. The hydrology of the region is equally complex, showing the headwaters of the East Fork Wallowa River and Eagle Creek, alongside notable lakes like Glacier Lake and the high-elevation Ice Lake beneath the peaks.
