1950 Map of Imlay SE

About this map

The White River winds through the northern portion of this landscape within the Pine Ridge Indian Reservation, creating a complex network of meanders and riverbanks. Surveyed in 1950, the area shows a distinct contrast between the river valley and the deeply eroded breaks that characterize the terrain. Local landmarks are sparse but significant for genealogy and local history, notably St Barbaras Ch situated near the river's path in the northeast. The drainage system is further defined by several named tributaries, including Medicine Root Creek and Clifford Creek, which cut through the southern uplands. This topographic study was produced as part of a larger federal initiative for the development of the Missouri River Basin, documenting the hydrologic and physical state of the reservation lands before significant modern changes.
