The Imnaha Wild and Scenic River carves a central corridor through this portion of the Wallowa National Forest. This protected riparian landscape is defined by deep drainages and high divides, notably Haas Ridge and Grizzly Ridge, which separate the myriad tributary creeks feeding the primary river system. Historical access and movement across this uneven terrain are marked by an established network of paths, including the Thorn Creek Trl, Corral Creek Trl, and Grizzly Ridge Trl.
