1952 Map of Trail City SW

About this map

The Cheyenne River Indian Reservation landscape is defined by the winding course of the Moreau River, which carves deep meanders across this South Dakota terrain. This 1952 field-checked survey reveals a sparsely settled region focused on the river valley, where St Marys Ch stands as a primary landmark above the northern banks. The intricate drainage network is mapped in detail, showing how intermittent streams like Handboy Creek, Marshall Creek, and Black Beaver Creek feed into the main river system. This map was produced as part of the Department of the Interior's post-war program for the development of the Missouri River Basin, capturing the topography of Dewey County before modern agricultural and infrastructure changes. The terrain is characterized by sharp elevation shifts between the river bottomlands and the surrounding breaks, with Swan Cr and Mullen Creek marking the southwestern reaches of the quadrangle.
