A major Pacific storm finally began breaking down our persistent high pressure today, and it had already started snowing from the middle of Little Cottonwood Canyon upward as we drove up canyon at 10:15. Why so late? Why bother going earlier? It was only going to get better as the day wore on.

And it did. My son, Marc_C and I enjoyed a surprisingly good day. Only four to six inches fell at varying intensities throughout the day, but it was dense, wet snow that covered up the underlying crust well. It was a psudo-powder day spent playing in the trees to enhance the visibility. Catherine's and runs on West Rust skied exceedingly well...anytime you get first tracks in places like Eagle's Nest or Christmas Tree it's a good day. Visibility in the fog and snow on the High T, however, was positively heinous.

The bulk of the storm, however, is expected to strike overnight. One to two feet are predicted, so tomorrow ought to be phenomenal. Tomorrow it's back to Alta, then Wednesday will probably be at Park City to pick over the scraps left by the out-of-state masses who primarily stick to the trails.

Speaking of tourists, they're definitely here, although today was anything but crowded. My son and I were already halfway down canyon when my phone rang. It was Marc_C, stuck trying to exit the Wildcat parking lot because some schmoe in a Nissan X-terra with California plates spun out trying to get up the hill out of the lot, and eventually had to back down. Apparently no one taught him how to put that truck into 4WD. :roll:
 
Marc,

You should take your son to The Canyons this week if you want some good scraps of fresh powder. That ski area is so large that there will be plenty of fresh snow in the trees to ski. Give AC a call and he can give you the tour.

I would, but I've got a season pass to PCMR that I need to break in, and that includes two "friends and family" tix. I'll give those to the wife and son.

I thought that Wasatch stuff stayed packed pow between storms this time of year. No?

Not necessarily. Last week (on Thursday, IIRC) six inches of 20% sludge fell upon the mountains when it was barely cold enough to be snow above 7,500 feet. That stuff promptly set up in the colder air that followed -- see the recent avalanche forecasts posted to this forum for more details. Furthermore, sun crusts formed in the relatively warm air, especially on west-facing and south-facing slopes. High altitude north-facing stuff stayed pretty good.
 
I took a few jibes at the weathermen for last week's prediction (1-3 inches at Mammoth, turned out to be 37 inches), and FTO's Scott Braaten was the only one who offered up an explanation. Normally Sierra and Wasatch storms gradually cool off with lowering snow levels as they progress. The unusual current situation (which Scott described as the jet stream punching through "dirty high pressure") seems to result in the opposite: storms start off cold and warm up. Thus the Sierra below 8,000 feet is getting some rain and the Wasatch got some Sierra Cement.

The other phenomenon is that the Wasatch is clearly the warmest region of the Rockies. So melt/freeze cycles are more common than in Colorado or Mammoth by my observation over the years. If it's not north-facing it can happen even in December or January. Of course in LCC/BCC it's usually resurfaced soon by the next dump.

I've skied in Utah a lot but have somehow missed the extremes. Very few big powder days, but also very few of the refrozen sludge days.
