Back to storm day skiing today, two days of sunshine was enough, bring on more powder.  Snowfall began in more earnest around 930am and by 1200 it was really gaining intensity. There was around a 1-2" of snow in the morning right at treeline within the start zone of "The Hose" and the adjacent slide path and by noon there was 5" and steadily falling. Within 200ft of ridgeline on leeward aspect, the snowpack was slightly stiff and punchable with a 5cm soft windboard layer. After that it was good, set up powder skiing with the light new layer of wispy graupel on top.  Did not get any results on ski cutting on stomping on wind loaded features. New snow was comprised mostly of graupel and I was a very wet ski tourer by the end of my travels.

The one point of interest I found was in Poop chute. The middle section of the chute  above the lower constriction was down to the rain crust and a  bit scratchy where I pulled to the side to let my sluff run past me. This dry loose snow ran a few hundred feet down the apron out of the chute but was minimal in volume. Was a good reminder that steeper terrain below 10000ft could harbor slick pieces of the rain crust where avalanches have pulled all subsequent snow off the ice. Good thing the rain didn't fall at higher elevations, would hate to hit that stuff in a more exposed line. 

Dug a pit at 9200ft, NW aspect in the trees. I wanted to check on the Valentines day rain crust and see if there was any faceting or weakness developing near, or at the layer. I did not find anything of concern, I performed a Deep Tap Test on the rain layer and there was no results. It was very stiff consolidated Pencil hardness snow both on top and below the rain crust.

Performed some other stability tests within the pit and did not get any suprising results. For the most part, bomber snowpack here with great stability. (see attached snowprofile)

On the drive up from Bishop at 800am, the tops of the higher peaks were already obscured, and when I rolled into Mammoth, of course most of the Ski Area and Mammoth Crest were completely enveloped in cloud. It started snowing with a bit more energy around 930am and by noon it was snowing hard. As I write this at 2pm, its dumping. Calm winds down in the lower elevations with moderate to strong S winds at Treeline. A bit of snow transport, but not really too much through early afternoon today. Sky was totally obscured.

-4C at 1100am
