The Dolores River carves a deep path through the center of this landscape, defining the dramatic topography of Dolores Canyon as it flows toward the northwest. This 2013 survey of the remote border between San Miguel and Dolores counties reveals a high-desert environment heavily managed for water storage. Numerous small reservoirs, including Wayne Rogers Reservoir Number One, Wayne Rogers Reservoir Number Two, and Rogers-Dalton Reservoir, are scattered across the mesas to support local ranching or wildlife. To the east, the terrain transitions into protected federal lands, where the boundaries of the Uncompahgre National Forest and San Juan National Forest meet. Local landmarks like Joe Davis Hill and Spud Patch Camp provide specific points of reference in a region characterized by canyons and the broad expanse of Disappointment Valley.
