About this map

The confluence of the Green River and the New Fork River dominates this Sublette County landscape, where the high desert terrain is carved by a sophisticated network of irrigation systems. Local ranching history is evidenced by the Olsen Ranch and an extensive array of water management features, including the Hanna Ditch, Hanna Number 2 Ditch, Sheep Ditch, and Crandall Ditch. These waterways demonstrate the essential engineering required to sustain agriculture in the arid Wyoming basins.

Prominent geological landmarks rise above the river valleys, most notably the towering Ross Butte and the broad expanse of The Mesa. The terrain transitions from these heights down through Bray Draw and North Alkali Draw toward the riparian zones. Transportation routes like Yellow Point RD and New Fork Bridge RD thread through the township lines of T30N and T31N, connecting isolated ranch sites across the Granite Wash.
