Additional activities include cross-country skiing, whitewater and flatwater canoeing and kayaking, sea kayaking, sailing, rock climbing and bicycle riding. The Club has about 2,700 volunteers, who lead roughly 7,000 trips and activities per year. The organization publishes a number of books, guides, and trail maps.
Appalachian Mountain Club was organized in 1876, incorporated in 1878, and authorized by legislative act of 1894 to hold mountain and forest lands as historic sites. The club was formed by the efforts of Massachusetts Institute of Technology Professor Edward Charles Pickering and Samuel Hubbard Scudder, who invited fellow Boston academics and vacationers to form a group interested in mountain exploration.
The club aims to preserve the beauty of mountain forests, waters, historic sites and resorts; to render them attractive to visitors and excursionists; to publish accurate maps thereof; and to collect scientific data concerning the mountains. The group helped map the White Mountains and in 1888 built the first of eight High Huts in the range, modeled on Alpine shelters.
