2018 Map of Mexican Flats

About this map

Mexican Flats and the surrounding high plains of Carbon County are defined by a complex network of ephemeral drainages and water management features. The landscape is carved by several prominent draws, including Windmill Draw, Barrel Springs Draw, and South Barrel Springs Draw, which lead toward the larger seasonal flows of Red Wash and Muddy Cr. This 2018 survey reveals the infrastructure of modern land management in an arid environment, notably the Dad Larsen Detention Dam 1593 Number 6 and the Twin Reservoirs near the southern boundary. These features, along with names like Coal Gulch and Blue Gap Draw, suggest a history of resource extraction and ranching utility. The grid of service roads, such as Wamsutter Rd and Straten Rd, provides the primary access across this open Wyoming terrain.
