1956 Map of Preacher Spring

About this map

Black Hills National Forest defines the topography of this mid-century survey, revealing a landscape of steep draws and vital water sources within the western South Dakota high country. The drainage network is particularly detailed, tracing the South Fork Castle Creek and numerous deep-cut ravines like Redbird Draw and Antelope Draw. This 1956 field check was produced in cooperation with the Atomic Energy Commission, reflecting the era's strategic interest in the geology of the Black Hills.
