About this map

The California Historic National Trail traverses this high-elevation terrain in Cassia County, following the path of the original Sublett Cut-Off. This route was a critical segment for westward migrants, and its preservation here within the Sawtooth National Forest allows for the tracing of 19th-century overland travel. The landscape is defined by the steep rises of the Sublett Range, where water sources like South Fork Fall Creek Spring and Shirley Creek feed into the high basin.

Modern water management is centered at the Sublett Reservoir, featuring a prominent Spillway and Head Gate system. Settled life is represented by the Broken Circle Ranch in the west, while the eastern portion of the map is marked by the remote drainage of Cold Spring Canyon and Hutchey Canyon. This 2001 revision highlights the intersection of pioneering history and the managed forest of the early 21st century.
