The high alpine environment of the Mummy Range dominates this 2011 survey, revealing a landscape defined by dramatic elevation changes and a complex drainage system. Central to the area’s geography is Comanche Peak, surrounded by high-altitude glacial features such as Mirror Lake, Emmaline Lake, and Cirque Lake. The map illustrates the water management infrastructure critical to this region, specifically Comanche Reservoir and Hourglass Reservoir, including the positions of Comanche Dam and Hourglass Dam. These reservoirs are fed by a network of tributaries including Beaver Creek and Fall Creek. In the lower elevations, the Cache la Poudre River and its South Fork provide the primary hydrological framework, while high mountain crossings like Mummy Pass and Flint Pass indicate the traditional routes through this high-altitude terrain.
