2023 Map of Tumble Mountain

About this map

Columbus Mtn and Tumble Mtn anchor this high-elevation landscape in Routt County, where the northern terrain descends into the riparian corridor of the Little Snake River. The drainage network is complex, defined by numerous seasonal and perennial flows including Willow Creek, Beaver Creek, and Gold Blossom Creek that carve through the surrounding peaks and ridges. High-country water management is evident at Lake Fork Reservoir and Boyer Reservoir, situated in the southern reaches of the quadrangle. The map captures a topography marked by distinctive summits such as West Gibraltar Peak and East Gibraltar Peak, along with unique landforms like Maria Bottoms and Circle Ridge. Access is limited to remote routes like Co Rte 129, reflecting the character of this sparsely settled portion of the Colorado wilderness near the headwaters of regional basins.
