About this map

The Salt River valley serves as a geographic anchor on this 2018 survey, straddling the border between Idaho and Wyoming. To the west, the steep, high elevations of the Caribou National Forest dominate the landscape, featuring prominent peaks like Black Mtn and the long stretch of Haderlie Ridge. This area is defined by its drainage systems, with numerous tributaries such as Jackknife Cr and Tincup Cr carving deep paths through the terrain toward the valley floor.

Settlement is concentrated along the river corridor, where the community of Etna and the historical Amesville Cem reside. The presence of the Freedom Air Ranch Airport and Double L Ranch Airport indicates the modern utility of the flat valley land, while named features like Hawthorn Hollow and Pat Canyon point to local landmarks used by generations of ranchers and outdoorsmen. The intricate network of local roads, such as Co RD 166 S and Stewart Trail Rd / CO RD 106, provides a clear view of the rural development patterns in Lincoln County.
