There will be periodic on mountain uphill enforcement sessions as well as on-going Patrol, Guest Services, and Mountain Ops spot checks. Our hope is that people will respect this system and self-regulate their behavior. An uphill strap with a sleeve for the picture pass is required while uphilling. The strap with picture pass is the first verification and can be acquired at a ticket office. The Aspen Card page of the app will display an indicator if you have valid Uphill access.
