Big Slide Peak
D2 windslab suspected to have occurred around December 30th observed off a heavily windloaded area beneath a cornice on Big Slide Peak. See avy ob.
Weak snow surfaces abound. Very beautiful large stellars (3-6mm+) in size were showing faceted growth. Very large surface hoar (up to 30mm) was observed laying flat, but covering snow surfaces in a high density fashion around bushes and trees. Much of these feathers formed while on the plants, but then fell off, a strange and interesting thing that resembles a deck of cards sitting atop the snow. The skiing was very fast, and fun due to the sharp, angular grains...
On steep SE aspects there was about 10cm of this weak snow covering a thin sun crust from 12/29. In some shaded slopes there was old, stiff wind slab underneath the weaker snow. Wind slab was also resting on faceted grains, though didn't have much energy.
Snowpack is still fairly shallow, some 50cm-80cm deep in the area, and we did find faceted grains near the base, though these were not super weak where we looked.
