Hi.
Just back from Rogers Pass and thought I would re-iterate the message about the buried surface hoar in sheltered locations below tree line.
Yesterdays storm, instead of clearing things out, have buried the surface hoar under a 60cm to 70cm slab.
We kicked off numerous small slabs along the side of Connaught Creek 200m from the hotel and on both sides of the stream (North and South aspects). Some of these slabs were fracturing on slope angles of less than 30 degrees.
Compression tests were in the Easy range and a Rutschblock on a 35 degree slope failed whilst cutting it out (RB score 1).
This highly reactive layer is likely to be an issue for awhile.
Take care out there.
Cheers.
Steve Blagbrough.
