1950 Map of Cascade Springs

About this map

The Cheyenne River winds through this 1950 South Dakota landscape, where the recently developed Angostura Reservoir meets a network of rugged canyons and natural springs. This survey records an essential moment in local education and land use, documenting the Brainerd Indian Training School along with scattered rural schoolhouses like Sheps Canyon Sch and Coffee Flat Sch. The territory is defined by its water sources, from the namesake Cascade Springs and Cascade Falls to more remote sites like Bridal Veil Spring and Cool Spring. These features supported the early ranching and agricultural operations found on Sorghum Flat and Coffee Flat. High points such as Flagpole Mountain and Roundtop Hill overlook a complex topography of named drainages, including Whaley Canyon and Hell Canyon, within the eastern reaches of the Harney National Forest.
