2015 Map of Red Desert

About this map

The Continental Divide defines the southern portion of this high-altitude landscape in Sweetwater County, where the topography transitions from the sweeping Latham Draw toward the rising elevations of the Wamsutter Rim. This 2015 survey illustrates a region shaped by modern transportation and early water management efforts, anchored by the settlement of Red Desert along the Interstate 80 corridor. Human presence is etched into the arid terrain through features like Fivemile Ditch and Threemile Ditch, which reflect the historic necessity of water diversion in this part of Wyoming. Further east, Big Hill provides a distinct landmark overlooking Frewen Lake, while a network of local routes such as Rasmussen Rd and CR 23 connect the sparse ranching and utility corridors of the Great Divide Basin.
