[6] Sacajawea Peak is the highest summit in the Eagle Cap Wilderness and the Wallowa–Whitman National Forest.

Both are connected to Hurwal Divide, a high ridge extending east and north from Sacajawea and Matterhorn.

A high pass connects Hurwal Divide to Chief Joseph Mountain, to the north.

These mountains and high ridges form a unit separated from the rest of the Wallowas by river valleys, with the West Fork Wallowa River flows north along the east edge and Hurricane Creek along the west.

[7] Sacajawea Peak is named for Sacagawea, the Shoshone woman who traveled with the Lewis and Clark Expedition.
