About this map

Collins Rim rises above a landscape defined by significant water management and high-desert drainage in this Lake County survey. This portion of the Fremont National Forest contains a complex network of reservoirs and waterholes, including Lane Reservoir Number Four, O'Keefe Reservoir, and Lucky Reservoir, reflecting the region's historical reliance on seasonal water storage for ranching and forestry.

The terrain is dissected by numerous drainages such as Twentymile Creek and Fifteenmile Creek, which flow through features like Long Canyon and the expansive Big Valley. Named water sources like Moss Spring, Rim Rock Spring, and Dismal Spring dot the slopes of Round Mtn, indicating the vital importance of reliable springs in this arid environment. Transportation is limited to forest and county routes like Co HWY 3-14, which follow the natural contours of the rim and canyon floors.
