The Ontonagon River system carves through the central portion of this 1951 survey, defining a landscape of steep ravines and industrial heritage in the Upper Peninsula. Copper mining legacy is visible near the settlement of Rockland, where the C Shaft Hill and the Irish Hollow Cem reflect the local history of the region's mining boom. To the west, the Victoria Dam and nearby Power Plant harness the river's descent, while the community of Victoria sits on the bluffs above.
