The Snake River carves a deep path through the heart of Hells Canyon, serving as the natural boundary between Oregon and Idaho. This terrain is defined by dramatic elevation changes, where river-level features like Rock Bar, Chimney Bar, and Two Bars sit thousands of feet below peaks such as Black Mtn, Lookout Mtn, and Cliff Mtn. The landscape is part of a complex of protected lands, including the Wallowa National Forest, Nez Perce National Forest, and Payette National Forest. Numerous rapids, including Granite Rapids and Hells Canyon Rapids, mark the river's course, illustrating the navigational challenges of this corridor. Scattered springs such as Coyote Spring and Jensen Spring provide vital water sources amidst the high ridges of Summit Ridge and Long Ridge, while the high plateau of Squirrel Prairie offers one of the few relatively level expanses in this vertical environment.
