About this map

The Snake River defines the northeastern boundary of this landscape, carving a path that creates distinctive landforms like Fruit Island, Dilley Island, and Cottontail Island. This high-desert terrain in Idaho is marked by a complex network of irrigation infrastructure essential to the region's agricultural life, including the South Canal, Deer Flat Low Line Canal, and Conroy Lateral. These waterworks contrast with the dry, dissected uplands where landmarks such as Elephant Butte, Liberty Butte, and the interestingly named Shares Snout rise above the surrounding gulches.

Local ranching and transport history is reflected in the arterial roads and small settlements like Sommercamp. The map traces the rugged drainage patterns of Squaw Creek and Opalene Gulch, which are accessed by a web of rural routes including Coyote Grade Rd and Sommer Camp Rd. This survey documents a transitional zone where the controlled flow of the river meets the natural topography of the Owyhee foothills.
