More than 150 years ago, the Huntington-Hitchcock Expedition was the first spend a winter atop Mount Washington. Led by two geologists, the 1870-1871 adventure occupied the summit to explore and document the mountain’s remarkable winter weather. The expedition paved the way for the U.S. Signal Service weather station on the summit, and served as the inspiration for re-occupying the summit by Mount Washington Observatory in 1932. This lecture is given by Curator Peter Crane, Ph.D., Gladys Brooks Memorial Library, the library of the Mount Washington Observatory.
