Snake River (scenic segment). Prehistoric archeological campsites along the banks of the river below Jackson Lake indicate seasonal use, especially near the confluence of tributaries (Pacific Creek and Buffalo Fork). As with the upstream segment, the Snake River was a major travel route used by American Indian tribes. Archeological resources on this portion of the Snake River are considered nationally significant. Beginning in the first quarter of the 19th century, fur traders gained access to the valley via former game trails along the river, which were used previously by seasonal American Indian occupants of the area. Twentieth-century homesteaders, dude ranchers, and conservationists took advantage of the river’s scenic and recreational attributes, as well as a strategic location to establish ranches and homesteads. National register-listed sites, such as Bar BC Dude Ranch, Menor’s Ferry river crossing, 4 Lazy F Dude Ranch, and Murie Ranch, sprang up along the Snake River and now stand as vestiges of the historic development along the river.
