About this map

Targhee National Forest dominates this mid-1980s terrain, providing a look at the drainage systems and peaks of Fremont County. The landscape is defined by the high point at Black Mountain and the prominent Big Grassy plateau. Waterways carve through the forest in every direction, from the larger South Fork and North Fork to smaller tributaries like Partridge Creek, Split Creek, and Snow Creek.
