About this map

Whitepine Ridge dominates the northern portion of this high-country landscape, where the headwaters of the Little Sheep Creek drainage system originate. This area is defined by the high-altitude boundary between the Beaverhead National Forest in Montana and the Targhee National Forest in Idaho. The topographic detail shows the complex hydrology of the region, featuring numerous named water sources such as Magee Spring, Shovel Spring, and Gibbs Spring that feed into the radiating forks of the creek.

The southern edge of the map follows the Continental Divide, which also serves as the state line between Montana and Idaho. Along this high ridge, the Continental Divide National Scenic Trl winds through the terrain, providing a modern trace across the same geographic markers used for historic county and state boundaries. The lack of major settlements and the presence of features like Shearing Pen Gulch suggest a landscape primarily utilized for seasonal grazing and high-altitude recreation.
