Tioga Pass, Sonora Pass, & Monitor Pass in California All CLOSED Due to Snow

9,943-foot Tioga Pass (hwy 120), 9,623-foot Sonora Pass (hwy 108), and 8,314-foot Monitor Pass (hwy 89) are all currently closed in northern California due to snow. 

The high country of California saw 12-24″ inches of snow in the past 24 hours and that was enough to close these mountain passes.  They’ve all been closed since yesterday morning.

There is a chance that Tioga and Sonora passes may remain closed for the winter season.  Monitor will reopen once they get the road cleared.

The road that drives right through Mammoth ski resort and into Devil’s Postpile is now closed for the winter.

“Mountain Passes closed due to snow in the High Country!

State Route 120 (Tioga Pass), State Route 108 (Sonora Pass), and State Route 89 (Monitor Pass) are closed due to snow.

State Route 203 from the Main Lodge to Minaret Vista is now closed for the season!” – Caltrans District 9
