In an article about skiing in a special section on Salt Lake City published April 28, it was stated that the cost of a daily adult lift ticket at the Deer Valley ski resort was $35. The correct price last year was $20 and it will be $ 23 in the 1982-83 season. To keep lift waiting times down, the resort limited the number of skiers on the slopes to 2,300. Reservations are recommended during peak holiday periods, though not required. The resort has no preference as to the ages of skiers.
