1950 Map of Imlay SW

USGS Topo · Published 1952

About this map

The White River carves a complex, meandering path across this landscape within the Pine Ridge Indian Reservation. This 1950 field check document shows a terrain defined by deep erosional cuts and drainage systems, including the notable Big Hollow Creek and Wind Creek to the north. The survey was conducted as part of the Department of the Interior's Missouri River Basin development program, recording the topography just before the mid-century's major hydrological shifts in the region. For local historians and genealogists, the map identifies specific landmarks like the St Mary Magdalene Cem located near the southern bends of the river, along with tributary junctions at Cottonwood Creek and Porcupine Cr. The intricate contour lines illustrate the stark contrast between the flat river bottoms and the sharply dissected uplands characteristic of this portion of South Dakota.
