1976 Map of Ensign Lake SW

About this map

Basswood Lake dominates the upper reaches of this 1976 orthophotoquad, representing a significant segment of the international boundary between Ontario and Minnesota. Unlike traditional topographic maps, this aerial perspective provides a literal view of the dense boreal canopy and the complex shoreline of the Boundary Waters region as it existed in the mid-1970s. The intricate network of waterways, including Sunday Lake and Snowbank Lake, illustrates the interconnected glacial landscape that defines the border country. This document preserves the exact physical state of the wilderness before later management changes, showing the raw texture of the forest and the clear, dark reaches of Manomin Lake and its neighbors.
