Me and my friend are thinking about (eventually) doing shasta, in a year or two. I was wondering what is the best time to go for a fun snow climb? Im thinking either avy gulch, or Casaval ridge both look like lots of fun (in the not fun sort of way). Im thinking either april or may? Of course i will have an avy course be then, and we are both proficiant in self arrest and crampon use. Like I said, we are looking for a good climb in winter conditions, and I would prefer snow, but not tons of postholing. Yes, I do realize that storms could come and dump any time, so snow conditions are really mercurial, but Im asking the best time to do shasta.
