Routt National Forest and White River National Forest converge in this high-altitude landscape, where the headwaters of the Derby Cr drainage system carve through the alpine terrain. The map reveals an intricate network of water management features, including the Lion Basin Ditch and S Derby Ditch, which redirect snowmelt across the slopes of Derby Mesa. These diversions illustrate the historical necessity of water rights and irrigation infrastructure even in the most isolated portions of the Colorado wilderness.
