Legendary 9,943-foot Tioga Pass opens tomorrow, May 11th. Tioga has been open to the pass from the East for a couple weeks. This has been great for access to Tioga from Tahoe or Mammoth or Reno, but if you’re in Sacramento or the Bay, it’s still too far.
Recent ski reports from Tioga Pass: April 30th Tioga Report, Wet Avalanche Tioga Pass April 27th, Carson Pass + Virginia Lakes + Tioga Pass April 26th
Now, with the pass about to be fully open in both directions, people in the Bay have a chance to zip directly up to Tioga Pass with no huge detour through Reno. This also gives them the chance to take Tioga Pass over to get to Mammoth taking about 3 hours off that drive.

Factors affecting plowing operations:
- 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.
Few trees on Tioga road, Rocks- yes
Thanks for this news. Headed up this week.
