Cadillac Mountain, first place to view sunrise in the United States from October 7 through March 6

Cadillac Mountain in Acadia National Park, at 1,530 feet (466 meters), is the highest point along the North Atlantic seaboard. It is one of over 20 mountains on Mount Desert Island (MDI), Maine that were pushed up by earth's tectonic and volcanic forces millions of years ago. Were it not for the once enormous glaciers that sheared off their tops, they would be even higher than what we see today. You can easily see the results of this on a smaller scale by viewing the slopes on the Porcupine Islands in the distance. The North side is on the left and the steeper slope, or the down side, is on the right east side. The glaciers crept across the land here from the left to the right (in a southerly direction) and stretched out to sea as far as 400 miles (644 kilometers)
