Hogback Mountain Ski Area was located across Route 9 on Mount Olga and relied exclusively on T-bars for ascent.

It operated from 1946 to 1986, using only natural snow, and blamed the cost of insurance for causing it to close.

Roughly 590 acres (2.4 km2) was purchased and given to the town of Marlboro as conservation land, known as Hogback Mountain Conservation Area.

Trails are semi-clear, as volunteers continue to keep some open and available to cross country skiers, backcountry skiers, hikers, and snowshoers.
