1952 Map of Whitehorse

About this map

The Cheyenne River Indian Reservation in Dewey County defines this early 1950s landscape, centered on the settlement of Whitehorse. This survey was conducted as part of a Department of the Interior program for the development of the Missouri River Basin, capturing the area's hydrology and small-scale infrastructure shortly after aerial photographs were taken in 1948. The terrain is marked by the winding course of the Moreau River and its confluence with the Little Moreau River to the south. Local landmarks like the Whitehorse Lake Spillway 1828 and a Flowing Well near the townsite indicate the critical importance of water management in this prairie environment. Genealogists may find interest in the local Cem located just north of the main settlement, providing a record of the community's footprint during this era of regional development.
