The shot above, of Kettle Point on Lake Huron, is one of many in a series taken in a line running from Pinery Provincial Park in Ontario, across Michigan looking north toward Saginaw (and its Bay), Grand Rapids, various towns on the Grand River, and then the shore of Lake Michigan, all while flying from Boston to Chicago on the way to Atlanta last week.
The woods near Kettle Point, and up the coast into Pinery Park, comprise the largest oak savanna in North America, left unspoiled because the sandy land beneath was bad for farming. The lines running through them are the remains of old shorlines. I won’t say “ancient”, because they aren’t. They’re markers of the rising land and shrinking size of the lake, which is actually a puddle left by the melting glacier that comprised an ice cap that recently came south as far as Long Island and Cape Cod, which were both built along its southern boundary of dirt and rock the glacier had carried there. In fact all the Great Lakes, and nearly every Lake in Canada, is but a dozen thousand years old, at its most elderly edge (this one here).
Kinda puts global warming in perspective. You could stand at any one of those lines at any time in the past 12,000 years, and speak of global warming as a progressive fact.
By the way, fall colors stand out in many of these pictures, if you look closely for them.
