Went up to check out whitney on the 29th and 30th of december last week.
There was the usual first roadsign block that you can drive around up in plce, but the 2nd roadbock that stops any vehicles about 2 miles from the trail head wasnt there. We went up in a tesla and nearly made it to the trail head parking lot but couldnt get enough traction around the last curves. a few 4x4s made it up fine. You can get up in chains probably. Even saw a toyota corolla up there. we parked close by only about a mile from the trailhead below where the snow wasnt as deep so at least we had to do less of a walk.

Theres currently about 2 - 3 feet of snow from 2 weeks ago that is still un-consolidated. difficult to put the tent pegs in such soft snow. Too early and not enough powder in the season for any real snow travel too. Also heard that the cables on the normal route up are still buried from a passing hiker we met.

I'll be waiting for the next big dumping of snow soon.
