About this map

The Sublett Range dominates this corner of Idaho, where the high-elevation landscape is defined by a network of drainage canyons and scattered mountain springs. The Minidoka State Bird Sanctuary occupies the central canyon lands, while the Sawtooth National Forest extends across the western reaches of the sheet. Settlement here is almost entirely centered on conservation and range management, anchored by the Sublett Forest Service Station near the headwaters of Sublett Creek.

Practical infrastructure for livestock and forestry is visible throughout the terrain, from the Pine Creek Reservoir in the south to the Storage Bins in the northeast. Ancient travel corridors are traced by a series of primitive routes through gaps like Summit Springs Pass, connecting numerous named water sources such as Yellow Jacket Spring and Wild Horse Spring. This 1970s record captures the region as a dedicated wildlife and forest resource area before modern development changed the character of many Western range lands.
