Chief Joseph Pass and Gibbons Pass anchor this high-altitude landscape along the Continental Divide, where the borders of Montana and Idaho meet. The 2011 survey illustrates a region defined by recreational development and historical transit corridors, including the Lost Trail Sports Area and the Lost Trail Pass Picnic Area. A complex network of drainage systems, such as the North Fork Salmon River and Moose Creek, carve through the terrain between Lewis and Clark Ridge and Saddle Mountain. Local landmarks like Cool Gulch and the Saddle Mountain Fire Area Point of Interest reflect the environmental management and natural history of the Bitterroot and Salmon-Challis national forest lands. For those tracing the geography of early western exploration, the presence of the ridge named for the Corps of Discovery provides a modern link to the historic 1805-1806 crossing routes used by Lewis and Clark.
