About this map

The Snake River winds through the volcanic and riparian landscapes of Southern Idaho in this detailed topographical study. The reservoir formed by Lake Walcott dominates the southwestern portion of the sheet, providing a vital aquatic habitat protected by the Minidoka National Wildlife Refuge. To the north, the terrain transitions into the stark, basaltic fields of the Craters of the Moon National Preserve, featuring the volcanic Wapi Flow.

Historic movement across this high desert is evidenced by the passage of the Oregon Trl near the southern riverbanks. Sparse ranching infrastructure, such as Owyhee Farms Ranch Rd and Irwin Ranch Rd, connects the open landscape to the small settlement area at DeWoff. Small geographic details like Smith Springs and Bird Island offer specific points of interest for researchers studying the hydrology and topography of the Blaine and Cassia County border.
