About this map

The Dolores River carves a deep path through this portion of Dolores County, defining the central topography of the Dolores Canyon. This 2016 survey illustrates a landscape primarily shaped by water management and public lands, with the eastern half of the map dedicated to the San Juan National Forest. The map details a sophisticated network of upland water storage including Rogers Reservoir, Dalton Reservoir, and the numerous numbered catchments like Big Water Reservoir Number One and Wild Bill Reservoir Number Eight.

Landmarks such as Mountain Sheep Point and Glade Point overlook the drainages of Secret Canyon and Big Canyon. Evidence of localized water sources is found at Bankston Spring and Tommy Spring, which likely served as critical points for cattle or wildlife in this arid environment. The presence of numbered county roads, such as Co RD 10 and Co RD 15, provides insight into the modern accessibility of these remote ranching and forest lands.
