About this map

Lake Sakakawea and the submerged channel of the Missouri River dominate this landscape, reflecting the massive hydrological changes of the mid-20th century. By the late 1970s, the reservoirs' reach is fully established, bordering Lewis and Clark State Park and the youth camp at Camp Cherith. These waters reshaped the bottomlands where Twin Valley and several named creeks once ran.

The map reveals a stark contrast between the inundated valley floor and the high, dissected plateaus of Truax and Twelve Mile. Uplands are marked by intermittent drainages like Chris Creek, Halfbreed Creek, and Long Creek, alongside markers of the region's geology such as a Scoria Pit and multiple sites labeled Flowing Well. This survey provides a precise look at the shoreline at a specific elevation, preserving the names of landmarks from the pre-dam era alongside modern recreational sites.
