Lewis & Clark National Forest encompasses the high-altitude terrain of the Big Snowy Mountains, where the landscape is defined by steep ridges and an extensive network of primitive paths. At the heart of the area, Crystal Lake serves as a central landmark for a system of routes including the Crystal Lake Loop Trl and the Grandview Trl. The geography is shaped by the transition from high summits like West Peak down through deep drainage systems such as Brooks Coulee and Porcupine Gulch.
