My wife has a family homestead on the northern coast of Maine, better known as Downeast. This area is filled with elongated lakes and ponds, rounded mountains, and large stretches of bare granite. All are relics of a not-so-distant past when Maine was covered by huge continental glaciers during the Pleistocene Epoch, or “The Ice Ages,” which started some 2.5 million years ago. Immense glaciers ebbed and flowed across the landscape and did not begin their final melting and retreat until just 18,000 to 11,000 years ago.
