Whitman National Forest land defines this section of Union County, where the upper reaches of the Grande Ronde River wind through narrow canyons. This 1960s survey documents a landscape focused on resource extraction and seasonal grazing, marked by high ridges like Jim Ridge. Prospecting activity is evident throughout the terrain, with several mining operations noted including the Aurelia Mine and the more significant Camp Carson Mine located near the headwaters of the river.
