Hi All,

Well, our camp is all set up and we just finished dinner.  Straits State Park has a “Dark Park” section.  The sky is partly cloudy right now, but it’s clearing to the west.  Hopefully, by dark, the sky to the NE will be clear enough to watch the tail end of the Perseid meteor shower.

Tomorrow’s 1st dive doesn’t start until 3:00 PM.  So, in the morning, we plan to visit Historic Mill Creek, about 11 miles away.  This mill is an accurate reproduction of a water powered saw mill dating from just prIor to the American Revolutionary War.  The British made dimension lumber in the mill all spring, summer, and fall.  Then, all winter, they hauled it on sleds across the frozen Straits of Mackinac to Mackinac Island.  This lumber was used to build Fort Mackinac out on the island.  Fort Mackinac is built on top of a 600 foot limestone bluff and is far more defensible against an enemy with a navy and cannons vs Fort Michilamackinaw built at lake level with only a wooden palisade.  By the time of the American Revolution, there had been Europeans living in the Straits area for 40-50 years.  Between the trees used for log cabins, the wooden palisade at Fort Michilamackinaw on the lower peninsula mainland (now Mackinaw City), and firewood, there was actually a local shortage of wood.  The British were forced to use dimension lumber vs logs in order to make more efficient use of the remaining trees.  In the summer, the park service will have costumed reenactors running the saw mill.
