About this map

The Snake River carves a deep path across this mid-century survey, anchoring a landscape where agricultural irrigation meets high-desert military operations. The complex network of the Milner Gooding Canal and various river diversions supports established settlements like Twin Falls, Jerome, and Buhl, illustrating the transformation of the Snake River Plain. In contrast, the southern and western reaches of the sheet are defined by the expansive Saylor Creek Aerial Gunnery Range and the remote high country of the Sawtooth National Forest.

Transportation remains tied to the corridor of the Union Pacific railroad and the historic river crossings at Glenns Ferry and King Hill. To the south, the topography transitions into the rugged drainage basins of the East Fork Jarbidge River and the West Fork Jarbidge River, reaching the northern edge of the Duck Valley Indian Reservation. Notable landmarks such as Balanced Rock and Wooden Shoe Peak provide orientation within the vast, lava-covered plains and volcanic buttes.
