USGS Topo · Published 1967About this map
Mississippi River navigation and the complex riparian landscape of the Wisconsin-Minnesota border define this mid-century survey. The massive infrastructure of Lock and Dam No 4 sits at the river's heart, controlling the flow through a labyrinth of side channels like Beef Slough, Terre Slough, and Iron Creek Slough. The topography transitions sharply from the low-lying Peterson Lake and McCarthy Lake to the steep bluffs of Rattlesnake Bluff and Alma Ridge.
