Just back from a few days of RAC in the Valemount area. Got to sled
up the old logging road from the mill on Blackman road, and up to
Cariboo Cat skiing's unload. We were basically on snowshoes, just
walked off the road a few feet...did see a couple of different aspects.
Along the road I stopped and did some probing and 3 quick pits.
there is about 110of snow at 4500ft, Ne facing.
The raincrust is down about 60-80cm.(see attach) Compression tests
here were easy to moderate!!! a "sudden collapse on the weak layers
near the rain crust.
Not as evident at treeline. We did see some older (1 week old ) slabs
on S aspects, cross loaded feature, ~ 70cm crown. Some newer activity
on the S side was also observed. A few small slabs were seen on the
NE aspects about 20cm down in the storm snow. could have been the
snowcat. Though harder compression were observed on both N and S
aspects at treeline, they were clean and repetitive.
Certainly worth paying attention now on all aspects. Not only is
there instability in the storm snow, but the deeper rain crust is
something we will all have to watch for a while to come...
