1976 Map of Basswood Lake SW

USGS Topo · Published 1979

About this map

The Basswood River defines the international boundary in this 1976 orthophotoquad, where the water-heavy landscape of the border country is captured in stark detail. This specific imagery was rectified from high-altitude aerial photography taken in May of that year, showing the intricate network of islands and interconnected waterways that span the line between Minnesota and Ontario. Unlike standard topographic maps, this photo-based record emphasizes the density of the forest cover and the complex shoreline geometry of the region before any later digital updates. The visual contrast between the dark lake waters and the textured canopy provides a direct look at the hydrology of the Boundary Waters area during the mid-1970s, serving as a primary reference for the state of the wilderness at that moment.
