About this map

The Green River meanders through this landscape, creating a complex system of islands and irrigation channels essential to Sublette County agriculture. Distinctive water management features like the Highline Canal, Whitewater Ditch, and Green River Island Ditch illustrate the engineering required to sustain ranching in the high basin. Near Fivemile Bridge, the river splits to form Tarters Island, while seasonal drainages such as Dry Piney Cr and Milleson Draw carve into the surrounding uplands.

Rising above the river valley, Castle Rock Red Hill provides a prominent landmark for travelers on Big Piney Calpet Rd. Local infrastructure is further defined by historic routes like Reardon Draw Rd and the proximity of Jackrabbit Reservoir. The topography transitions from the wet lowlands of Long Island to the carved relief of Chapel Canyon, reflecting the area's dual nature as a fertile riparian corridor and an arid rangeland.
