1967 Map of Marine on St Croix

About this map

The St Croix River defines the eastern boundary of this mid-century landscape, where the settlements of Marine on St Croix, Copas, and Otisville represent the historic riverfront development of Washington County. The terrain is defined by a dense concentration of glacial water bodies, from the sprawling Big Marine Lake to the smaller Square Lake and Big Carnelian Lake. This era shows a transition toward recreation and preservation, evidenced by the expansive William O'Brien State Park and educational landmarks like the Science Museum and Amherst H Wilder Day Camp Area. Local genealogy is well-served by the presence of Oakland Cemetery and Elim Cem, while industrial activity is noted at the northern Gravel Pit and a southern Quarry, marking the literal foundations of the local economy.
