Belknap Mountain, in central New Hampshire south of Lake Winnipesaukee, is the highest point in Belknap County and the central summit of the Belknap Mountains, named for Jeremy Belknap, the eighteenth-century preacher and historian. Though not especially tall by New Hampshire standards, its isolation from the White Mountains gives it exceptional topographic prominence, ranking it among New England’s fifty most prominent peaks. An active fire tower stands on the summit, and the mountain lies on a drainage divide within the Merrimack watershed. Geologically, it belongs to the White Mountain Magma Series and preserves evidence of Jurassic volcanic activity, deep erosion, and a complex igneous history.
