It's been such an unusual winter that we haven't had to mention snow conditions
very much. Spring-time is often when large avalanches occur as the winter
snowpack weakens. However, a recent incident shows that the current conditions
are highly unusual for the Coast Mountains.
At the weekend, a large avalanche in the Brandywine area caught out two
snowmobilers and took them for a several hundred-metre ride. Thankfully neither
was injured but it brought to light a significant issue with the coastal
snowpack right now. The avalanche was up to a metre deep at the crown, the
result of the recent storms and was sitting on a persistent weak layer, left
behind after the long period of dry weather. This has made the snowpack highly
susceptible to large avalanches - class 3 (which can destroy a car) or even
class 4. Even worse, they can be triggered remotely - in other words, you could
set off a slide that affects other people, but not you.
Here's the report and a photo to give you an idea of the terrain and size of the
avalanche:
