Most human development is in the western half of the town along the Connecticut River and New Hampshire Route 10, known as the Dartmouth College Highway. The eastern half of the town is mostly forest. The town is home to four great ponds: Post Pond, Pout Pond, Trout Pond, and Reservoir Pond. Holts Ledge is a cliff that faces east and is part of the Dartmouth Skiway. The edge of the cliff is fenced to protect falcons. The highest point in town is the summit of Smarts Mountain, at above sea level. A fire tower, which was built in 1915, is visible from miles away atop Smarts Mountain and sets it apart from other local mountains.
