2020 Map of Lake Walcott SE

About this map

Raft River meanders through the southeastern portion of this Idaho landscape, carving a path near the mouth of Heglar Canyon. This high-desert terrain in Cassia County is defined by its rectilinear grid of township and range lines, intersected by the modern corridor of Interstate 86 and Highway 30. The map illustrates a transitional zone where the open range meets the more varied topography of the canyonlands. Local travel is marked by established routes like Yale Rd and Heglar Canyon Rd, which follow the natural contours of the drainage systems. The survey also captures the administrative boundary between Cassia and Blaine counties in the northeast corner, providing a clear view of how political borders were surveyed across this expansive topography. Researchers will find a landscape that remains primarily defined by large-scale land divisions and the vital watercourse of the river.
