About this map

Mining activity and irrigation engineering dominate this arid landscape on the Wyoming-Colorado border. Poison Basin is marked by a concentration of early 21st-century mining operations, including the Alpha Claim Group Mine, Murphy Mine, and several numerically-designated claims like the Cedar Hills One-twelve Mines. The terrain is defined by the Red Creek Rim and the Poison Draw, which descend toward the Little Snake River at the bottom of the map.

A network of water management features highlights the area's agricultural infrastructure, with numerous reservoirs such as Spragg Reservoir and Long Walk Reservoir situated along the drainage of Red Creek. Significant irrigation ditches, including the Heeley Ditch, Darr Ditch, and Gibson Blair Ditch, traverse the river bottom near County Hwy 4, illustrating the effort to redirect water across this high-desert basin.
