Maine
The Appalachian Mountains extend through Maine. It’s western borders have rugged terrain and there are long sandy beaches on the Southern coast. In contrast, the Northern coast (known locally as Downeast) is mainly rocky promontories, peninsulas and an actual fjord. Maine has 3,478 miles of Coastline. In addition, the coast contains more than 3,000 islands and thousands of intertidal ledges.
There are 10 peaks over 4,000 feet with the highest being Baxter Peak (5,276 ft.) on Mount Katahdin in Baxter State Park. Katahdin is also the Northern most terminus of the Appalachian National Scenic Trail.
