About this map

The Keya Paha River winds through this mid-1960s landscape, serving as a primary geographical anchor where the border between South Dakota and Nebraska meets. The small settlement of Mills sits just south of the river, marked by a sparse network of unimproved roads and light-duty trails that trace the drainage basins of Wolf Creek and Indian Creek. Along the northern edge of the sheet, the Rosebud Indian Reservation Boundary defines the political landscape, crossing through the northern reaches of Gregory County.

Genealogists and local historians can locate the Olive Branch Cem tucked near a spring south of the river. The topography is defined by significant elevation changes, most notably at Nets Peak, which overlooks a series of draws and seasonal Springs. This survey reflects the rural character of the Keya Paha region before modern infrastructure changes, capturing the established township lines and family-named landmarks of the era.
