[MCR] mt athabasca avalanche standard route-addendum-

[Public Mountain Conditions Report]

To add to my previous MCR report. The size 2 avalanche on the standard ramp
on mt Athabasca occurred above the Serac cliffs. It was triggered by two
skiers on their way up. One was swept 200m down, over the serac cliff, and
fully buried 15cm under. The other person slid for 30m but stopped short of
the serac cliffs and was buried waist deep. They both were able to dig
themselves out, no injuries. They report 2 weaknesses in the snowpack at
this location upon their approach, one down 40-50cm was the culprit, and
another 1m down that did not release. 70% of the ramp is still in place.

Other parties coming off Columbia Icefields report intense wind transport
last night with slab development on lee aspects. Temperatures ranged from
-4 to -8 yet they said it felt "warm".
