Acadia National Park is a national park located in the U.S. state of Maine. It reserves much of Mount Desert Island, and associated smaller islands, off the Atlantic coast. Created as Lafayette National Park in 1919, it was renamed Acadia in 1929 and is the third oldest national park east of the Mississippi River, following Thousand Islands (1904) and Point Pelee (1918) in Ontario.The area was originally inhabited by the Wabanaki people.While he was sailing down the coast of what is now Maine in the fall of 1604, Samuel de Champlain observed a large inshore island. He wrote:”That same day we also passed near an island about four or five leagues in length, off which we were almost lost on a little rock, level with the surface of the water, which made a hole in our pinnace close to the keel. The distance from this island to the mainland on the north is not a hundred paces. It is very high and cleft in places, giving it the appearance from the sea of seven or eight mountains one alongside the other. The tops of them are bare of trees, because there is nothing there but rocks. The woods consist only of pines, firs, and birches.” He named it Mount Desert Island.Over four centuries later, the area remains essentially the same.
