1950 Map of Imlay SE

About this map

Pine Ridge Indian Reservation land dominates this 1950 field-checked survey, revealing a landscape defined by the serpentine path of the White River. The topography is intensely detailed, showing the complex erosion patterns and badlands formations characteristic of the South Dakota plains. Small communal markers are visible against the dramatic terrain, most notably St Barbaras Ch situated near the riverbanks. The drainage system of the region is traced through the winding courses of Medicine Root Creek and Wind Cr, which carve through the reservation's high ridges. This map captures the intersection of natural geography and tribal land boundaries before modern development altered the local infrastructure, offering a clear view of the area's physical state at mid-century.
