1968 Map of Corral Creek

About this map

Continental Divide crests across this 1960s survey, marking the high-altitude border between Montana and Idaho. The landscape is defined by the steep transition from the Centennial Valley in the north into the timbered slopes of the Targhee National Forest and the Centennial Mountains. In the far southwest corner, the small settlement of Humphrey sits along the Union Pacific railroad line near the banks of Beaver Creek. The drainage patterns here are complex, with the Lima Reservoir collecting headwaters in the northwest while numerous seasonal and permanent streams like Corral Creek and Long Creek carve through the mountainsides. This map captures the region when primitive roads and a lone Radio Tower were the primary indicators of modern development in an otherwise high-mountain wilderness.
