Clearing of the Tioga Road begins on or about April 15 each year and usually takes between one and two months. Predicting when these roads will open is not possible, even in late spring, because weather in April and May can affect plowing progress significantly.
Note: Snowpack shows the percent of average for the Tuolumne River drainage (which includes the higher elevation areas of Tioga Road).
* Notes by year

2017: John Muir Trail closed early due to damage, but would have closed for the season on January 18
2016: Mist Trail closed for a few weeks in March due to weather/conditions
