1971 Map of Dixon NE

About this map

Lake Francis Case dominates the eastern half of this landscape, its underwater contours preserved here from 1947 data to show the valley floor before the Missouri River was fully harnessed. The terrain is defined by a series of deep drainage cuts including Landing Creek, Fivemile Creek, and Dry Creek, which carve through the high plateaus of La Roche. This 1971 field-checked survey highlights the complex border geography where Lyman, Gregory, Brule, and Charles Mix counties meet near the Rosebud Indian Reservation Boundary.
