Cadillac Mountain, Acadia National Park, Maine — At 1,532 feet, this is the highest vantage point along the North Atlantic seaboard. During certain times of year, the summit receives the rays of the first rising sun within the United States. The pea, composed of pink granite, is perched above a forest of spruce and pitch pine. Among the granite slabs are tiny sub-alpine plants such as cinquefoil, squat, gnarled trees, wild blueberries and various sized boulders. The view of the Maine archipelago is unsurpassed, with the Cranberry Islands foremost in the southwest.
