Ski Butternut is a ski resort in Great Barrington, Massachusetts, located on Warner Mountain in The Berkshires.
The ski area was first opened by the New Haven Railroad as Warner Mountain Ski Area in the 1936-37 ski season. The area was later known as G-Bar-S Ranch.
Channing and Jane Murdock took control of the area in 1963, naming the area after the large groves ofbutternut trees located in the basin of the mountain.
The mountain currently features 22 trails, ten ski lifts, two terrain parks, a tubing area, and a PSIA-affiliated ski school. In the off-season, the mountain hosts a number of summer concerts and festivals, including the annual Berkshires Arts Festival.
