America's newest national monument is situated in Maine's North Woods. On Wednesday, President Obama designated 87,500 acres of the forest as the Katahdin Woods and Waters National Monument, marking the 413th preserved area in the National Park Service, National Geographic reports, and Maine's second national monument. The designation came at the request of Burt's Bees founder Roxanne Quimby, who donated the land valued at $60 million to the federal government this week in honor of the National Park Service's 100th anniversary.
