1966 Map of Twin Butte

About this map

Twin Butte rises as a central landmark within this mid-1960s topographic survey of the Idaho backcountry. The landscape is defined by the high divides of Pettibone Ridge and Long Ridge, which separate a dense network of drainages including Pettibone Creek, Squaw Creek, and Bear Creek. This era of the Nez Perce National Forest is characterized by its primitive access, with the map showing an extensive system of Pack Trails and standard Trails as the primary means of movement through the Selway Bitterroot Wilderness. The geography reveals a complex system of V-shaped valleys and high summits like Elk Ridge, where water flows from the heights of Santa Creek and Wahoo Creek down toward the southern reaches of Paradise Creek and Cub Creek. The absence of roads emphasizes the protected, wild character of the region during this period of federal land management.
