Bar Harbor, ME to Cobscook Bay State Park, ME

I spent most of the day at Acadia National Park.  Its a lot like the rest of the Mid-Coast region of Maine, but without all the houses.  The most prominent feature is Cadillac Mountain, which has a summit of 1,528 feet and no trees at the top.  I doubt that its above the treeline, so it must be the fact that its solid granite.  Here is the view of Bar Harbor from the summit:

Acadia National Park has four parts.  The primary part, which includes Cadillac Mountain, is on Mount Desert (pronounced de-SERT) Island.  The other parts are the Isle au Haut, part of Baker Island, and the Schootic Peninsula on the mainland.  The acquisition of the Schootic Peninsula portion included a strange condition.  The couple who owned it were English, and they took exception to the park's original name, which was Lafayette National Park.  So Congress changed the name to Acadia National Park and the couple conveyed their property.

I traveled to Schootic Point on the Schootic Peninsula to see what the fuss was about.  I did come upon an interesting feature.  Running through the granite at the seashore were gabbro dikes (I originally called them basalt).  This indicated that volcanic activity had pushed flowing magna into crevices in the granite.  Dikes like these are generally at the vertical or a large acute angle.  These deposits, as seen below, are roughly horizontal.  All this means is that after the dikes had cooled and solidified, they and the granite were subject to an upheaval that turned them on their side.
