About this map

High-altitude sagebrush steppe and water management infrastructure define this landscape along the border of Sublette and Sweetwater counties. Water is a primary focus of the mapping, with the Little Sandy Reservoir Number 2 and Little Sandy Cr providing critical resources for this arid region. The presence of Chambers Ditch illustrates the early and ongoing efforts to divert water for local agricultural or livestock use.

Transport through this isolated terrain is marked by the Sublette Cutoff and several major rural arteries, including Big Sandy Elkhorn Rd and Parson-Little Sandy Rd. These routes represent the modern iterations of historic corridors used by travelers moving across the high plains of Wyoming, where surveyors have carefully delineated township and range boundaries across the township lines of T28N through T26N.
