About this map

Lake Sakakawea and the Missouri River dominate this portion of the North Dakota landscape, revealing the complex water systems shaped by the Garrison Dam project. The topographic detail highlights the transition from the river's main channel to the branching inlets of Writing Rock Coulee and Bear Den Creek. Elevated landmarks like Blue Butte provide significant topographical relief against the surrounding plains, serving as traditional navigational points for the region's inhabitants.

Surface infrastructure includes Bia Rd 4 and Turnley Ridge Rd, which wind through the terrain near Foreman Coulee. This map documents the hydrologic patterns and land use within the Fort Berthold area, showing how modern roadways intersect with old natural drainages such as Boggy Creek. It is an essential record for understanding the intersection of local tribal land management and federal water engineering in the early 21st century.
