Dolores River carves a deep path through the center of this terrain, where the high-altitude topography of San Miguel Co meets Dolores Co. The landscape is dominated by the massive Joe Davis Hill and the dramatic drop into Dolores Canyon, illustrating the isolation of this western Colorado canyon country. Water management is a primary feature of the high plateaus, evidenced by a series of high-altitude impoundments including Wayne Rogers Reservoir Number One, Sand Rock Reservoir, and Pony Reservoir.
