I can ditto what Nemo said, she went in a few days before I did.
I remember hearing all sorts of stuff about the snow in the Sierra’s last year, mostly from a bunch of people that didn’t know what they were talking about. One trail angel basically told us all that we were stupid for going in on the 17th. We heard reports of people going in, postholing for miles and then turning around. There was much anxiety and trepidation in KM. And then…it was great! Basically from Whitney to Dicks Pass, whenver we got above a certain altitude, there was near total snow cover. We plowed through it, made snowmen, postholed a bit, kicked steps up passes, glissaded down them and had a hell of a time. Yes, it was exhausting, but well worth it.
The creeks were a bit sketchy at times. The combination of fast moving, ice cold water and slippery round boulders can be unnerving at times, but it’s all part of the experience. Just remember to have respect for what you’re doing and you should be fine.
