1950 Map of Cascade Springs

About this map

Brainerd Indian Training School and several rural schoolhouses define the social landscape of this Fall River County territory during the mid-century. The topography is dominated by the complex canyon systems of the Harney National Forest, including Alabaugh Canyon and Sheps Canyon, which drain toward the winding Cheyenne River. A significant transformation of the river valley is evident with the presence of the Angostura Reservoir, showing its normal elevation and spillway levels shortly after construction. Local life centers around the thermal features and natural landmarks of the region, such as Cascade Springs, Cascade Falls, and Bridal Veil Spring. The transition from the steep terrain of Stage Hill to the agricultural reaches of Sorghum Flat and Coffee Flat illustrates how early 20th-century settlers adapted their livelihoods to the varied South Dakota breaks.
