Deer Valley has never allowed uphill traffic or backcountry access within their resort boundaries. In response to issues they’ve had with backcountry skiers they’ve recently added language to clarify the prohibition on any uphill traffic inside the resort.
Deer Valley’s mountain safety policies outline that Deer Valley Resort is closed to all winter sports activities at all times except during their operating hours. It is considered trespassing for anyone, with or without a Deer Valley pass, to enter the resort through roped boundaries. Summers said that backcountry skiers accessing the resort through Empire Pass is also illegal, and people who do it are trespassing. Charges could include a class B misdemeanor.
Summers said its considered trespassing to enter the closed boundary through a rope line, and that it creates a safety risk for mountain ski patrol.
