America's Coolest Ghost Towns

Flagstaff, ME

Lake Flagstaff got its name from an interesting historical tidbit: Benedict Arnold’s troops once planted a flag here. But back then, Flagstaff was also above water. In 1950, plans for a hydroelectric dam meant the whole town would be submerged. While most buildings were moved or destroyed, some sites—the occasional chimney, for instance—can still be visible from the water’s surface, if you know where to look. You can get a map of the site from the Northern Forest Canoe Trail, or take a tour in a pontoon boat. You can also see artifacts and more about the lost town at the nearby Dead River Area Historical Society.
