From obs: "Toured up into the Blackmore/Elephant basin today to get a sense of the snowpack ahead of the upcoming storm cycle. I poked around and dug in a few spots, trying to observe variations in snow depth and to observe where the snow has been faceting. Every pit I dug, ranging from N to SE facing, had faceting near the ground, all of which reacted in stability tests, if stubbornly. The most interesting test result was an ECTP21 in this layer of basal facets. That pit was dug in a large wind drift. I saw no propagation in any other pit or test.

Strong wind gusts were moving large amounts of snow in the alpine, while below treeline they did not exceed moderate speeds and wind transport was non existent. Large drifts were present on lee slopes, while more exposed windward slopes had little to no snow.

Otherwise the snowpack has behaved as one would expect. Solar aspects and exposed flats have a 2-3cm thick sun crust on the surface, and a further complex of crusts throughout the shallow snow pack. Snow depth ranged from 0 - 100 cm throughout the basin, and was generally thinner on solar aspects. Pretty bad skiing all around, not excluding the rock gardens on the skinner out." Photo: W.

From e-mail: "Photo attached from near top of hyalite peak, 11/2. Cracking in recent hard wind slab, I had to really jump hard to make this. Walked on many other hard slabs that were well bonded. Highly variable snowpack. I think you'd be most likely to get into trouble by popping out a small hard slab pocket like this and getting magic carpeted into some thinly covered terrain." Photo: B.

From obs: "1-3 mm faceting in front of the Montage. Clear skys and mid 20 temps"
