About this map

Tri Basin Divide serves as a critical hydrological and historical point within the Bridger National Forest. This high country is defined by the convergence of major drainage systems, including the Greys River flowing north and La Barge Creek moving south. Historically significant paths intersect here, most notably the Emigrant Trail and its associated Lander Cutoff, which provided westward travelers a vital route through the mountains. The presence of the La Barge Guard Sta and the Gaging Sta on Lander Cutoff Creek reflects a landscape managed for both preservation and resource monitoring. From the heights of Commissary Ridge to the secluded Poison Meadows, the map captures a network of legacy pack trails like the Wyoming Range Trail, once essential for navigating this remote corner of Lincoln County.
