Explosive avalanche control have produced slab avalanches up to size 2.
Snowpack Summary
Mother nature has been pummeling the Sea to Sky region over the last few days. Over 100cms of snow that fell since last weekend has now settled to about 70cm. Recent southwest winds have consistently hovered in the strong to extreme category and wind drifts have been reported up to 3 metres high. The recent storm snow is resting on a variety of older snow surfaces. These surfaces include previous cold, dry low density snow which may have had seen some faceting, old wind slabs, and crusts. It is reasonable to think that any new avalanche activity may step down to any of these interfaces.Previous concerns about deeper persistent weak layers appear to have diminished. Snowpack depths at treeline are in the region of 260 cm.
