This fascinating account explores the significance of the Chicago Portage, one of the most important--and neglected--sites in early US history. A seven-mile-long strip of marsh connecting the Chicago and Des Plaines Rivers, the portage was inhabited by the earliest indigenous people in the Midwest and served as a major trade route for Native American tribes. A link between the Mississippi River and the Atlantic Ocean, the Chicago Portage was a geopolitically significant resource that the French, British, and US governments jockeyed to control. Later, it became a template for some of the most significant waterways created in the nineteenth and twentieth centuries. The portage gave Chicago its name and spurred the city's success--and is the reason why the metropolis is located in Illinois, not Wisconsin.
