More of Mackinac. This is Mackinac.Follow in the footsteps of the fur trade. From 1780 to about 1835 Mackinac Island was the principal summer depot and supply center for the upper Great Lakes fur trade. Pelts gathered at Mackinac were shipped to eastern United States and European markets. During the golden age of the American Fur Company, great wealth was produced on Market Street.Historic Downtown Mackinac includes the Benjamin Blacksmith Shop, a working 1950s-era blacksmith, the American Fur Company Store and Dr. Beaumont Museum, and the McGulpin House, perhaps the oldest private residence in Michigan. Admission is included with a Fort Mackinac or Historic Downtown Mackinac ticket.
