It is all over the news that the Sierra are going to get pounded with massive snowfall,http://www.cnn.com/2008/US/weather/01/04/california.storms/?iref=hpmostpop
Here is a story I posted a few minutes ago on the SkiVT-List (I have family & friends up there) Perhaps a few here are also interested in such snowfalls.
I've got my eye on it. I'll be in LA on business the week of Jan. 28 and will follow that with a couple days of play at Mammoth, one of the very best ski mountains anywhere. I do a lot of business trips to LA, many in the winter.
However it doesn't have to be winter. I have skied there on July 4, riding lifts. I have also skied Mt. Conness in the Tioga Pass backcountry in late June. First trip to Mammoth was with my son in Mar. 95. It started to snow as we were driving there. It was the leading edge of a "Pineapple Express" string of storms, just like what they are going to get now. An hour after we arrived the roads were closed and remained closed for a week while it snowed 9 feet. It stayed cold and the snow was light & dry; I'd call it British Columbia powder rather than Utah powder. We never got up to the corniced ridge; too much wind and avy danger too high. All lifts were closed for an hour or so a couple of times due to lightning. Mammoth has a town shuttle bus with 4WD & chains which we took from town to mtn. each day. It was a record snow year and in places the groomers had dug 20 foot deep trenches so the chairs wouldn't bottom out. It was an amazing week.
When the winds are howling and avy danger is high there are many alternatives. You can XC ski up to the Mammoth Lakes (Lake Mary loop) on the Tamarack Trails touring system. It is wind sheltered, out of any slide run out zones, and very beautiful. June Mtn., 10 miles away and on the same lift ticket as Mammoth, is a little skied gem. It is much more wind sheltered than Mammoth and has some of the best moderate angle trees anywhere that are safely out of any run out zones. Few SO CA skiers venture into trees. You can have uncut powder all day and come back next day for more of the same.
