Like north suburban Lake Forest, Gary was built by investors with a plan, but in the case of this development in northwestern Indiana, the plan was industrial rather than religious and educational. The U. S. Steel Corporation developed the core of Gary in conjunction with its steelworks plant. Developers created outlying portions of the city independently. As in Chicago, the added areas fit easily into the existing grid. In this early twentieth-century map, the platted portions in a largely empty landscape conform to the township and section lines envisioned more than a hundred years earlier for the land ordinance of 1785.
