2013 Map of Allison Creek

About this map

The Salmon River cuts through this high-elevation landscape in Lemhi County, serving as the western boundary for the massive Salmon National Forest. This interior region of the Lemhi Range is defined by sharp elevation changes, from the river corridor up to prominent features like Long Ridge. Transportation in the area relies on a network of drainage-following routes such as McKim Creek Rd and Allison Creek Rd, while the presence of Old Stage Rd suggests the historical movement of goods and travelers along the river valley. The map documents numerous ephemeral and perennial water sources, including McKim Cr and Allison Cr, which have carved deep features like the Dry Gulch into the mountain slopes. This 2013 survey provides a clear view of the interface between protected national forest land and the rugged Idaho backcountry.
