The settlement of Imnaha serves as the focal point for this rugged terrain in Wallowa County, situated at the confluence of several significant canyons and waterways. The Imnaha River carves its path through the center of the sheet, joined by tributaries such as Big Sheep Cr and Little Sheep Cr. This landscape is defined by its dramatic elevation changes, with prominent landmarks like Hartshorn Butte and Grizzly Ridge overlooking deep basins and canyons.
