About this map

The expansive wetlands and high-altitude waters of the Red Rock Lakes National Wildlife Refuge dominate this part of the Centennial Valley. The landscape is a complex hydrologic network where Lower Red Rock Lake and Upper Red Rock Lake are fed by numerous mountain drainages, including Odell Creek, Red Rock Creek, and Tepee Creek. To the north, the terrain rises sharply toward Patchtop Mtn and Landon Ridge within the Beaverhead National Forest.

Remote access is provided by a thin network of unimproved routes such as N Valley Rd and Landon Ridge Rd, which skirt the boundary between Beaverhead Co and Madison Co. This area serves as a critical watershed, where the headwaters of the W Fork Madison River originate near the continental divide. The presence of features like Sparrow Slough and Nye Cr highlights the intricate riparian environment that has remained largely undeveloped into the twenty-first century.
