Bob Sisco of Michigan uncovered a reference to Sugarbush Ski Area on a Wikipedia entry for Youngstown Ridge. According to comments on the Wikipedia page, there was a small ski resort and restaurant located on Sugarbush Ridge, named the Sugarbush Ski Resort. (No relation to Vermont’s Sugarbush Resort, which is still active and thriving.) Sugarbush Ridge and Solomon’s Temple Ridge are two neighboring mountain ridges, collectively known as Youngstown Ridge. The area is located southeast of Latrobe and Youngstown, Pennsylvania.
DCSki does not currently have any more details about this ski area.
