About this map

Arsenic Mtn and the Sawtooth Range dominate this landscape within the Bob Marshall Wilderness and Lewis & Clark National Forest. The map documents a complex drainage system where Arsenic Creek, Whiskey Creek, and Circle Creek descend toward the Sun River valley. Near the southern boundary, the waters of the North Fork Sun River and South Fork Sun River converge at the head of Gibson Reservoir.

Evidence of human activity is primarily limited to a dense network of backcountry routes, such as the Mortimer Gulch Trl and Fish & Game Cabin Trl, illustrating the area's management for conservation and recreation. The presence of Reclamation Flats and Medicine Springs near the reservoir suggests historical infrastructure and natural features that shaped early access to this mountainous corridor along the Teton and Lewis and Clark county line.
