2012 Map of Poison Meadows

About this map

Tri Basin Divide serves as the hydrological centerpiece of this high-altitude Wyoming landscape, where the headwaters of several major drainages diverge. The terrain is defined by the winding course of the Greys River and its numerous tributaries, including the E Fork Greys River and Mink Cr. To the west, the Smiths Fork valley is accessible via Smiths Fork Rd, passing near Crystal Lake as it heads toward the higher elevations of Wagner Pass. This area is characterized by vast meadows used for grazing and transit, most notably Poison Meadows and LaBarge Meadows in the south. The complex network of watercourses, such as La Barge Cr and Shale Cr, illustrates the importance of this watershed for regional water management and historical livestock movement in the Bridger-Teton area.
