About this map

Angostura Reservoir dominates this landscape, having recently transformed the valley where the Cheyenne River meets its tributaries. This 1950 field check captures the area just after the completion of the Angostura Dam Spillway 3198, part of the Missouri River Basin project. The reservoir’s rising waters reach into the deep draws of Horse Camp Draw and the rugged canyons of the western shore, including Red Canyon and Adams Canyon.

Beyond the water’s edge, the map reveals a rural landscape transitioning toward mid-century development. Harney National Forest covers the high ground to the west, while the Hot Springs Municipal Airport sits on the plateau to the northeast. Local education is still anchored by rural landmarks like Lithia Sch and Coleman Sch, providing essential markers for genealogists tracing families in this corner of Fall River County during the early post-war era.
