Maine is the easternmost state in the contiguous U.S. It is known for its scenery-jagged, rocky coastline, low rolling mountains, and its heavily forested interior. Much of Maine's geography was created by heavy glacial activity at the end of the last ice age. The Portland–South Portland–Biddeford metropolitan area, consists of three counties in Maine, anchored by the city of Portland and the smaller cities of South Portland and Biddeford.
