Huntington Ravine is a glacial cirque on Mount Washington in the White Mountains of New Hampshire. It is named for , the Principal Assistant to State Geologist (1836–1919) for the Geological Survey of New Hampshire. Of the four major cirques on Mount Washington (Tuckerman and Huntington ravines, , and the Great Gulf), it has the steepest and highest headwall. Only one hiking trail ascends Huntington Ravine toward Mount Washington's summit; that trail, the Huntington Ravine Trail, crosses a boulder field, ascends a talus fan, and winds steeply up the center of the cirque's headwall, requiring several tricky scrambling moves that may be intimidating for less-experienced (or more acrophobic) hikers. All other portions of the headwall are too steep to climb safely without climbing gear and technical expertise. Several popular rock-climbing routes, such as the Pinnacle route and the Henderson Ridge, do ascend the ravine, and in the winter the Pinnacle Gully is especially popular as an ice-climbing challenge. Because the ravine is higher and more exposed to the elements than most other climbing areas in the eastern United States, rock and ice climbing — and even hiking — are risky and weather-dependent. Avalanches, icefalls, and hypothermia have killed climbers in Huntington repeatedly in recent years, and the hiking path is usually not passable until late May or early June. (en)
