The opening of the Tioga road depends on the ability of Park service and Caltrans crews to clear the road of snow and rockfall. They do their best. A Memorial Day weekend opening looks doubtful. The opening of the road has nothing to do with Mammoth Mountain activity.
Ulmstead Point and the east side of Tioga Pass are especially problematic, because of avalanches and rock slides. If you've even driven into the Park from the east on opening day, you'd know what I mean.
