The Slumgullion Earthflow and Slumgullion Slide dominate the northern landscape of this Mineral County survey, where the high-altitude divide between the Gunnison National Forest and Rio Grande National Forest is clearly defined. This region is a complex of volcanic plateaus and alpine meadows, featuring prominent landforms like Jarosa Mesa and Snow Mesa. High-altitude transportation is concentrated along the route crossing Slumgullion Pass and Spring Creek Pass, while foot travel follows the Continental Divide National Scenic Trail. Water management is evident through the presence of the Rito Hondo Reservoir and the Continental Reservoir at the southern edge, which capture snowmelt from peaks like Horsethief Mtn and ridges such as Gardner Ridge. The map illustrates the headwaters of numerous drainages, including Slumgullion Cr and the various forks of Cebolla Cr.
