The ongoing celebration of the Outing Club’s 100th anniversary hits a high point October 10, when the club sponsors the first ever single-day hike of the Appalachian Trail by a college. The 2,175-mile trail will be divided into sections, and participants will be given banners to photograph for a digital essay. To volunteer for a section or to shuttle and board hikers, send an e-mail to atinaday@ dartmouth.edu. No Governor Sanford jokes, please.
