AAR's - After Action Reports

Archaeologists have excavated prehistoric fishing camps on Mackinac Island and in the surrounding areas. Fishhooks, pottery, and other artifacts establish a Native American presence at least 700 years before European exploration, around AD 900. The island is a sacred place in the tradition of some of its earliest known inhabitants, the Anishinaabe (Ojibwa) tribes, who consider it to be home to the Gitche Manitou, or the "Great Spirit". According to legend, Mackinac Island was created by the Great Hare, Michabou and was the first land to appear after the recession of the Great Flood.[21] The island was a gathering place for the local tribes where their offerings were made to Gitche Manitou, and it was the burial place of tribal chiefs.

The Jesuit Relations (1671) contains a long description of Mackinac Island,

"its fisheries, its phenomena of wind and tide, and the tribes who, now and in the past, have made it their abode. A favorite resort for all the Algonkin tribes, many are returning to it since the peace with the Iroquois. On this account, the Jesuits have begun a new mission, opposite Mackinac, called St. Ignace. Thither have fled the Hurons, driven from Chequamegon Bay by fear of the Sioux, “the Iroquois of the West." [25]

The Relations also indicate the tremendous strategic importance of Michillimackinac/Mackinac Island as "the central point for all travel on the upper Great Lakes, and for a vast extent of wilderness and half-settled country beyond" to First Nations and Europeans (prior to the arrival of railroads).
