Steve,
Much of SR 120 is closed for the winter. You would need to hike, snowshoe, or ski something like 10 miles to get to Tioga Pass from the east. I’ve heard of snowmobile shuttles, but that’s probably not an option right now with so little snow down low. Mt. Dana is a short distance but 3,000 feet of elevation gain from Tioga Pass. You would be on the north side of Mt. Dana, so it’s probably covered in snow, maybe some deep snow. There is probably very little real ice, but I would take crampons, ice axe, snowshoes, and ski poles. Either that, or wait until July when you can just stroll up in trail runners.
