About this map

Lake Francis Case dominates the landscape along the Missouri River in this early 1970s survey, marking the border between Gregory and Charles Mix counties. The map captures the reservoir with underwater contours derived from 1947 data, showing the transformed river valley at an indefinite elevation of 1354 feet. Along the eastern bluffs, the Rosebud Indian Reservation Boundary cuts across the dissected terrain of Castalia and La Roche. Local landmarks like Trinity Ch and a nearby Cem provide specific points of interest for genealogists tracing family ties to these rural townships. Significant drainage systems including Whetstone Creek and its North Fork flow from the west, while recreational access is noted via Picnic Areas and a Boat Ramp near Platte Creek.
