About this map

Collins Rim defines the high desert topography of this region, separating the drainage of Twentymile Creek from the expansive flats of Big Valley. The landscape is dotted with evidence of early 21st-century back-country use and rangeland management, including scattered outposts like Collins Cabin, Mate Cabin, and Haw Cabin. These small structures, along with Barley Camp, suggest a persistent human presence tied to the seasonal needs of timber or livestock within the Fremont National Forest.

Water is a critical feature in this arid environment, marked by numerous named water sources such as Rattlesnake Spring and Dismal Spring that feed into Fifteenmile Creek. To the north, the elevation levels out toward Big Lake and Lucky Res, providing a stark contrast to the steep descent from the rim. The inclusion of the Levee and various named springs underscores the vital importance of water control and natural reliable flows for anyone navigating or working this part of Lake County.
