Avalanche Summary
A few small loose dry avalanches were reported over the weekend and into Monday. One large (size 3) slab avalanche was triggered remotely on a southwest aspect on Sunday. The avalanche failed on a crust layer 20-30 cm deep, but showed surprisingly wide propagation.
Snowpack Summary
Additional snow amounts of around 15 cm Monday night has brought storm snow totals to approximately 40 cm in this region. This storm snow is resting on a variety of surfaces, including crusts on southern aspects, hard wind-affected snow in exposed locations and soft faceted snow in sheltered areas. Two layers of weak surface hoar crystals are buried in the snowpack between 45 and 80 cm deep, which were buried in mid-February and early-February. The layers may be associated with a melt-freeze crust on southerly aspects. Avalanche activity on these layers has tapered, but it may still be possible to trigger one of these layers in isolated areas such as steep cutblocks and large open glades.
