Lake Superior dominates this nautical-heavy quadrangle, showing the convergence of three distinct Michigan counties far offshore. The 2014 survey captures the maritime boundaries where Keweenaw, Houghton, and Marquette counties meet beneath the surface of the world's largest freshwater lake. This digital-age mapping emphasizes jurisdictional lines over the open water of the Keweenaw Peninsula's coastal reaches. In the northwestern corner, the grid identifies legal subdivisions within Township 56 North, Range 30 West, including sections 16 and 21, which represent some of the only terrestrial references in an otherwise aquatic study.
