October 8, 1982:

October 8th and 9th, 1982 a record-breaking snowstorm for so early in the Fall paralyzed the northern Black Hills with three to six feet of heavy, wet snow and winds of 40 to 70 miles an hour. Some snowfall amounts included 41 inches at Galena, 36 inches at Lead, and 23 inches at Deadwood. Five to six feet of snow was common in the higher elevations. The heavy wet snow caused numerous problems. The roof of a clothing store in Lead collapsed under the weight of the snow and several other businesses were damaged. The roofs of at least three trailer homes also collapsed. The combination of strong winds and heavy snow broke tree branches (causing extensive timber damage), power lines and telephone poles. Damage was done to 40 miles of power lines, including 30 broken power poles. Some residents were without power for five days. The city of Deadwood was without electricity and fresh water for at least three days.
