Where is the plow?

A lot of you have been asking “When is Tioga Pass going to open?” As of right now it’s anyones guess. Warm weather will make some parts easier but others, like the avalanche zones by Olmsted Point (there are 26 of them along the road) could become much, much more dangerous. The photo above shows the plow close to Raisin Creek.

So why does it take so long to plow the road?

Here’s a list of factors that influence how long it’ll take the road to open.

• 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.
