The cartographic records of the Wisconsin Territory, primarily documented by the Department of War, provide invaluable insights into the region's historical development. These records include detailed surveys of rivers, proposed piers, and territorial boundaries, showcasing the efforts of notable figures such as Capt. T. Jefferson Cram and Lt. L. Sitgreaves. Organized by government units and record groups, particularly Record Group 77, these maps and surveys not only highlight the natural resources and infrastructure of the time but also serve as essential resources for researchers and historians interested in the evolution of Wisconsin's landscape and governance. By preserving these records, the National Archives ensures that the rich history of the Wisconsin Territory remains accessible for future generations.
