Challis National Forest and Sawtooth National Forest converge in this high-altitude landscape of central Idaho. The map centers on the high basins of Casino Lakes and Garland Lakes, where the drainage of Big Casino Creek and Rough Creek flow north toward the Salmon River. A high-country landing strip, Rough Creek Airport, sits perched above the deep valleys, indicating the specialized aviation required for access in this era. To the northwest, the Salmon River Campground marks the recreational corridor along the river, while a Mine and Gravel Pit suggest small-scale resource extraction. A network of Jeep Trails provides the primary means of traversal through the dense contour lines, passing landmarks like Lookout Mtn and Rough Lake. The boundary between the two national forests and the transition into the northern end of Sawtooth Valley characterize the southern portion of the survey.
