From June 10-12th, I drove over Carson Pass, backpacked up Wolf Creek to near Wolf Creek Pass and drove back over Ebbetts Pass. There is tons of snow and it made me sad.
The eastside is a little less snowy. It was snow free for the first 2.5 miles up Wolf Creek, then patchy until about 4.5 miles in. That puts the snow line at about 7,200ft, in contrast with the west side where the snow line appeared to be continuous around 6,500ft. Snow depth is highly variable, but anything above 7500ft would be constant snow. The high country would be better on skis. Depth at 8,000 ft ranged from zero (certain aspects) to over ten feet, with an "average" of perhaps 6 feet. In Wolf Creek, snow was consolidated spring snow and only a little (1 foot deep) postholling was experienced in the afternoon.
I'd guess that the PCT is nearly entirely covered in snow with only rare aspects being snowfree, but the valleys generally still being snow covered.
I'm rethinking entering the high country until late July.
