1964 Map of Last Chance

About this map

Henrys Fork dominates this portion of the Targhee National Forest, carving a wide, serpentine path through the eastern Idaho landscape. The map captures the area during the mid-1960s, a period when this stretch of river was anchored by the settlement of Last Chance and the prominent Railroad Ranch. The topography is defined by the sharp rise of Osborne Butte and the extensive water system of Silver Lake, Golden Lake, and Swan Lake. This survey illustrates a transition in land use, where traditional ranching at sites like Railroad Ranch existed alongside developing recreational infrastructure such as the Osborne Springs Campground and Riverside Campground. Local navigation is marked by the Osborne Bridge and several jeep trails, including the Hatchery Butte Road, which provided access to the timber and river valley before significant modern expansion.
