About this map

The Grandjean settlement sits at the confluence of several mountain drainages in the early 1970s, serving as a gateway to the high peaks of the Sawtooth Range. The landscape is dominated by the intersection of the Boise National Forest and Challis National Forest, with the South Fork Payette River carving through the center of the sheet. High-altitude features like Mt Zumwalt and Zumwalt Lake stand north of the river, while the eastern portion of the map transitions into the Sawtooth National Recreation Area.

This 1972 field-checked survey highlights the early infrastructure of the Sawtooth Wilderness, featuring a network of Pack Trails, a Forest Service Station, and Corrals used for backcountry access. Geological interest is noted at Sacajawea Hot Springs along the riverbanks, illustrating the thermal activity and recreational utility of the area before modern wilderness management shifted the footprint of such sites.
