1966 Map of Thornburgh

About this map

Thornburgh (Historical Site) marks a significant point of interest near the junction of Milk Creek and several irrigation works along the border of Moffat and Rio Blanco counties. The landscape transitions from the high peaks of Thornburgh Mountain and Uranium Peak down to the water resources of Aldrich Lakes and Wyman Reservoir. This mid-century survey, updated with late-1980s data, illustrates the specialized land use of the region, where industrial features like the Thornburgh Gas Field and various Prospects sit alongside the traditional infrastructure of the White River National Forest. The presence of several water-management systems, including Ferguson Ditch No 2 and Wilson Ditch, highlights the essential nature of water rights in this high-altitude environment, while a network of pack trails and jeep trails provides access through Yellowjacket Pass.
