About this map

Salmon National Forest defines this high-elevation landscape in Lemhi County, where a complex network of drainages flows toward the major arterial of Panther Cr. The topography is marked by significant elevation changes, from the heights of Porphyry Ridge and Little Deer Creek Ridge down to deep ravines like McDonald Gulch and French Gulch. This 2017 survey reveals the intricate hydrography of the region, including the headwaters of Blackbird Cr, Musgrove Creek, and Woodtick Cr.

Evidence of resource management and historical land use is visible in the placement of Sawmill Gulch and the named access roads such as Blackbird Creek Rd and Yellowjacket Rd. These routes follow the natural contours of the land, connecting the various forks and gulches that characterize this part of the Salmon River mountains. The map provides a contemporary record of forest boundaries and water systems, showing how the drainage patterns of Slippery Cr and W Fork Blackbird Cr shape the local terrain.
