About this map

The Targhee National Forest dominates this section of Fremont County, where the high-elevation landscape is defined by the canyon-forming waters of the Fall River and its numerous tributaries. Significant hydrological management for the region is evident through the presence of the Marysville Canal and Yellowstone Canal, which divert water from the river system to support agriculture further downstream. Local landmarks like Porcupine GS and the dramatic Cave Falls mark this area of the forest.

Water is the central theme across the terrain, with dozens of named drainages including Squirrel Creek, Conant Creek, and Rock Creek carving through the volcanic plateaus. High-country water bodies like Porcupine Lake, Horseshoe Lake, and Bear Lake are joined by unique geomorphic features such as the Robinson Creek Breaks and Long Meadows, reflecting a landscape used for both resource management and conservation.
