About this map

The South Fork Payette River winds through this high-altitude landscape, serving as a primary corridor for the small settlement at Grandjean. Established at the junction of several mountain drainages, the site includes a Forest Service Station, Corrals, and a Footbridge, reflecting the area's role as a logistical hub for wilderness management and recreation in the early 1970s. The geography is defined by the steep transition from the Boise National Forest into the high peaks of the Sawtooth Range.

Hydrothermal activity is noted at Sacajawea Hot Springs along the riverbanks, a landmark for travelers long before the formal designation of the Sawtooth Wilderness. Notable peaks and alpine water bodies like Mt Zumwalt and Zumwalt Lake overlook a network of watercourses including Baron Creek and Wapiti Creek, illustrating the drainage patterns that feed the larger Payette system. This survey documents the boundary between Boise and Custer counties during a period of expanding federal conservation efforts.
