The Continental Divide crests across this landscape, separating the high-altitude headwaters of the Rio Grande Reservoir from the southern reaches of the San Juan National Forest. Near the northern shore of the reservoir, historical infrastructure remains visible at the Stage Station and nearby Ruins, while a Resort and Boat Ramp indicate the area's development for recreation. High-country water management is evident through the Raber Lohr Ditch and Fuchs Ditch, which redirect snowmelt across the rugged terrain.
