1979 Map of Castalia

About this map

Castalia stands at the northern edge of this South Dakota landscape, where the prairie begins its descent toward the expansive waters of Lake Francis Case. This 1970s survey documents the complex topography along the Missouri River corridor, featuring the sharp ravines of Castalia Creek, Platte Creek, and Dry Creek as they drain into the main channel. The map provides a detailed view of the Rosebud Indian Reservation Boundary as it meets the riverbank, alongside conservation and hunting territories like the Gray State Public Shooting Area and the southern State Game Refuge. For those tracing local history, the map includes the inland Friesland Cem and several Flowing Wells situated in the winding draws of Cedar Creek. The drainage patterns and underwater contours of the river reflect the significant engineering changes that reshaped this portion of Charles Mix County in the mid-20th century.
