1972 Map of York Island

USGS Topo · Published 1975

About this map

Fort Peck Lake dominates this landscape, its waters filling the Missouri River valley and various coulees across the Charles M Russell National Wildlife Range. This 1970s survey captures the shoreline where three counties meet — Valley, McCone, and Garfield — following the complex geometry of the impounded river. The presence of Fort Peck Dam at the northern edge is the defining engineering feature, creating a series of deep-water bays like Sturgeon Bay and Catfish Bay that transformed the original river channel. On the water, York Island stands as a prominent landmark between the main lake body and the Dry Arm. Grounded markers like the Radio Tower near the dam and various lights at Markles Point and Haxby Point provide essential navigational references for the area's recreational and wildlife management infrastructure.
