About this map

Salt River meanders across the Idaho-Wyoming border in this mid-1960s survey, marking the agricultural heart of the Salt Lake Valley. The settlement of Etna sits at the base of the high timberlands, where irrigation features like the Baker Ditch and East Side Canal define the local water management essential for valley ranching. The landscape transitions sharply from the flat river bottom to the dense reaches of the Caribou National Forest to the west, which is accessed via the Black Rock Trail and several other pack routes.

Evidence of early infrastructure is visible along the river, including a Powerplant and a Gaging Station near the forest boundary. For those tracing the history of recreation and backcountry work in Lincoln County, the map identifies a remote Cabin near Jackknife Creek and the Tincup Campground at the southern edge of the sheet. The network of drainage basins, from Newswander Creek to Tincup Creek, illustrates the complex hydrology that feeds the valley from the western peaks.
