Fort Michilimackinac is up at the northern tip. It's a reconstructed copy of the fort that stood there during the French-Indian War and Pontiac's Revolt.
Pontiac tried to unite the tribes to rise as one against the whites. The idea was to have one massive blow to push them off the seaboard. Not everyone wanted to play though. Despite this, they succeeded in capturing almost all the frontier forts including Michlimackinac. They did this by trickery.
The Indians assembled with their lacrosse ball and sticks and proceeded to play a game outside the fort. While the commander (Capt. George Etherington -sp) was warned, he didn't believe the warnings. At a signal, the ball was "knocked" into the gate where a lot of the womenfolk were waiting. Hidden beneath their blankets were their weapons which the warriors then used to make short work of the garrison. The good Capt. E. was taken prisoner and then ransomed back.
Pontiac's success did not repeat itself at the larger forts including the ones at Detroit, Pittsburg (Fort Pitt) and Ligonier. The Indians were discouraged as they dislike siege warfare and then suffered a defeat when Col. Henry Bouquet (1/60 Royal Americans) defeated their attempt at Bushy Run to stop his relief column from reaching Fort Pitt.
A peace was signed in 1764 and the forts and white captives returned to the British. Funny but many of the captives had grown use to Indian lifestyle are returned back to the Indians.
Anyway, Michlimackinac is one of the major sites I've yet to visit.
