About this map

The Saint Joe River winds through the northern reaches of this Idaho landscape, carving its path alongside the Skookum Canyon. This terrain is defined by a series of prominent summits and ridges, most notably the Three Sisters formation which includes Middle Sister Peak, East Sister Peak, and West Sister Peak. These peaks are surrounded by a dense network of drainages such as Sisters Creek, Prospector Creek, and Nugget Creek, names that reflect the region's mineral prospecting history.

Logistics and access in the early 21st century relied on forest roads like the Avery-Timber Creek Rd and Sisters Creek Rd. Evidence of recreational and administrative use is visible at Forest Cabin, Packsaddle Campground, and Turner Flat Campground. From the heights of Siwash Peak and Mount Chenoweth down to the depths of Trickle Gulch, the map reveals a wilderness structured by high-elevation peaks and the river system that drains them.
