Come spend a night in the heart of the Sierra just outside Yosemite National Park at Yosemite Pines RV Resort and Family Lodging.

The Word is Out: Tioga Pass Opens May 11th 2013

| April 24, 2013

I know you’ve been dying to know when it will open so wait no more. Tioga Pass opens May 11th!!!

Factors that affect plowing and opening of the Tioga Road include:

  • Avalanche zones (26 potential areas). The Olmsted Point avalanche zone requires a lot of work, including application of charcoal over the snow to help with melting and blasting the snow slab to make it safer for personnel.
  • Heavy snow pack slows the whole operation.
  • Trees that have fallen across the road and been buried in the snow. These can cause substantial damage to the equipment and result in a stop to all operations until they’re cleared.
  • Rock slides buried by the snow. These can cause substantial damage to the equipment and result in a stop to all operations.
  • Snow storms during the opening require a stop to Tioga Road operations and in order to plow and sand the park roads.
  • Road repairs and ditching and brushing operations once snow has melted back enough.
