2001 Map of Sublett Troughs

About this map

California National Historic Trail corridors weave through this section of the Sawtooth National Forest, tracing a legacy of western migration across the Sawtooth Range and Sublett Range. The map highlights the Hudspeth Cut-Off, a significant alternate route for emigrants seeking a more direct path during the gold rush era. This high-elevation terrain is defined by its critical water sources, including Sublett Spring, Eyrie Spring, and the Pine Creek Reservoir, which supported both livestock and travelers in an arid environment. From the heights of Eyrie Peak down to the distinct Rock Sublett Troughs, the landscape is a network of deep drainages such as Ward Canyon and Heydlauff Canyon. Smaller features like the Storage Bin and numerous named seeps like Kossman Seep reflect the managed grazing and forestry uses of the late twentieth century.
