1976 Map of Ensign Lake SE

USGS Topo · Published 1979

About this map

Ensign Lake and the surrounding wilderness of northern Minnesota are captured in this mid-1970s orthophotomap, which uses aerial photography to detail a landscape defined by water and rock rather than roads or towns. The international boundary between the United States and Canada is visible where it traverses the connected waters of Knife Lake and Carp Lake, following the historical path of the Ontario and Minnesota border. This specific survey provides a clear view of the complex shoreline of Ima Lake and the narrow corridor of the Knife River, illustrating the glacially-sculpted terrain of the Boundary Waters region. Unlike traditional topographic maps, the orthophoto format reveals the literal texture of the forest canopy and exposed Canadian Shield, highlighting the isolation of these interconnected lake systems.
