2022 Map of Casto Reservoir

About this map

The Uncompahgre National Forest dominates this high-altitude landscape on the Uncompahgre Plateau, where a complex network of trails serves a terrain defined by seasonal waterways and high-country ranching. Water management is central to the area's geography, anchored by the Casto Reservoir and Big Cr Reservoir, which feed into Big Creek and Little Creek. The map documents the persistent human presence in these elevations through sites like Big Creek Ranch and the interestingly named Dead Horse Pasture.
