Gem Valley and the western slopes of the Bear River Range dominate this Idaho landscape, where the town of Grace serves as a central hub for agricultural and water management activities. The map reveals an intricate network of irrigation infrastructure essential for high-altitude farming, including the Tanner Canal, Bench Canal, and Allen and Cherry Ditch. These waterways diverge from the Bear River as it passes through Black Canyon, supporting the dispersed settlements of Niter and Bench. To the east, the terrain rises sharply into the Cache National Forest, carved by numerous drainages like McPherson Canyon and Nelson Canyon. This 2017 survey also documents local landmarks such as Ice Cave Knoll and the Grace Cemetery, while the presence of Simpson Airport highlights the region's modern connectivity despite its traditional rural character.
