Vermont is in New England and borders the other  Massachusetts, New Hampshire, New York, and the Canadian province of Quebec to the north. Several mountains have timberlines with delicate year-round alpine ecosystems, including Mount Mansfield, the highest mountain in the state; Killington Peak, the second-highest; Camel’s Hump, the state’s third-highest; and Mount Abraham, the fifth-highest peak. The National Park Service administers the Marsh-Billings-Rockefeller National Historical Park (in Woodstock) and the Appalachian National Scenic Trail.
