 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.
