Blackwater is a private ski area which serves the school and other various high schools in the region, and is open to the public on a few occasions. Below is more information from Chuck.

Cut in the mid-1960s, the Blackwater Ski Area originally operated with a 1500-foot rope tow, serving the students at Proctor Academy, in Andover.  In 1970, the school purchased a used T-bar in Michigan, and installed it to replace the original lift. In recent years, that T-bar was replaced with a newer one purchased when King Ridge closed in nearby Sutton. A new O’Connor lift provides access to the lower slopes and both 15 and 30-meter ski jumps, while providing a descent to the T-bar that services the top of the hill.
