The rugged Maine coast is full of wonderfully rocky formations. The best example of these can be found in Acadia National Park, but the rock formations don't end just because the park does. Take Winter Harbor, Maine for example. Much of the area where the ocean meets the land is dominated by rocks which have likely been in place for centuries...if not longer. I stumbled upon this collection of probably hundred pound rocks just off the coast. The rocks are quite prominent and aren't going anywhere anytime soon. And that, my friends, is a large part of what separates the Maine coast from, say, North Carolina.
