About this map

Lake Sakakawea dominates this landscape along the border of McLean and Mercer Counties, illustrating the modern geography of the Missouri River valley. The map details the jagged northern and southern shorelines of the reservoir, including the deep inlets of Good Bear Bay and Red Butte Bay. These waters cover historic bottomlands, leaving only the higher plateaus and coulees, such as Buffalo Rock Coulee and the drainage of Sixmile Cr, as visible landmarks of the original terrain. Evidence of early settlement remains on the higher ground south of the lake, specifically the Congregational Cem located near Bia Rd 22. The presence of Bureau of Indian Affairs routes like Bia Rd 20 reflects the area's ongoing importance within the regional transportation network and its connection to surrounding communities.
