About this map

Brownlee Reservoir dominates the western corridor of this landscape, marking the submerged course of the Snake River along the border. The terrain is defined by a series of steep drainages and canyons that feed into the reservoir from the east, including Billy Gulch, Louse Canyon, and Ryan Gulch. These features illustrate the deep erosion patterns of the high desert plateau as it drops toward the river canyon.

In the eastern portion of the map, the landscape opens into the Henley Basin, a significant topographic depression where Henley Creek originates. This area is connected to the wider region by Rock Creek Rd, one of the few improved thoroughfares in a territory otherwise defined by ephemeral watercourses like Perkins Creek and Grouse Creek. The network of named creeks, such as Little Rock Creek and Hog Creek, suggests a landscape historically utilized for livestock and resource management.
