1964 Map of Last Chance

About this map

Henrys Fork snakes through this portion of the Targhee National Forest in eastern Idaho, defining a landscape of wetlands, volcanic buttes, and mid-century recreational development. The small settlement at Last Chance sits near the northern boundary, supported by a local Landing Strip and proximity to the river. Further south, the map reveals the complex hydrology of the region, where Thurmon Creek feeds into Silver Lake and Golden Lake before meeting the main river channel. The presence of the Railroad Ranch and the community of Osborne highlights early land use patterns, while the Osborne Springs Campground and Riverside Campground indicate the area's established role as a destination for outdoorsmen and travelers. Terrain features like Osborne Butte and Hatchery Butte rise above the surrounding flats, providing distinct landmarks for navigators and local historians.
