Hard to predict the future.. We have been hit with wierd snowstorms here for the past month. If I am getting 3-4 feet, I bet the sierras are just dumped on!
I flew over them a couple weeks ago.. so white that distinguishing features were hard to see. 1/2 dome looked like a little skulll cap.
I would imagine the Parks Service would have info on that. No doubt the 80 is open, south of that.. Caltrans may know, or county roads sites.
