1966 Map of Jack Springs

About this map

Dinosaur National Monument defines the western edge of this landscape, where the high elevations of Douglas Mountain overlook a complex network of draws and springs. The map documents a sparsely settled portion of Moffat County in the mid-1960s, a place where human activity is marked by isolated landmarks like the Warrick Ranch and Basset Cabin. Water is the critical factor in this arid terrain, as evidenced by the numerous mapped water sources including Dripping Rock Spring, Strong Spring, and the perennial flow of Vermillion Creek which features localized Falls.
