The heaviest snow fell in Yellowstone Park where the Two Oceans Plateau SNOTEL site reported 28 inches of new snow. The Absarokas, Tetons, Wind River, Salt River, and Wyoming Ranges all reported new snow totals of over 20 inches. The heavy snow resulted in difficult travel conditions and road closures.
