1969 Map of Patch Skin Buttes SE

About this map

Forest City and the surrounding river bluffs are depicted here shortly after the massive Missouri River impoundment projects reshaped the South Dakota landscape. The map centers on the expansive Missouri River-Lake Oahe, showing the high-water margins and controlled inundation areas that transformed the old river valley. Along the western shore, the Cheyenne River Indian Reservation Boundary follows the former river channel, marking the division between Dewey and Potter counties. On the eastern shore, the Dolphus Peninsula extends into the lake, hosting the Whitlocks Bay Recreation Area (West Unit) with its Public Landing and Campground. The presence of the Swift Bird Training Center and nearby Swift Bird Bay reflects the institutional and recreational development of the late 1960s, while a small Landing Strip and various Gravel Pits indicate the local infrastructure supporting this transition from a traditional river valley to a reservoir-based economy.
