[MCR] Widespread Natural Avalanche Cycle in Banff/Yoho Kootenay

A Parks Canada helicopter flight over Sunshine
and Lake Louise today showed a wide spread avalanche cycle is currently
happening. Numerous size 1.5's to size 3's were observed at the alpine
and treeline elevations. In addition a number of smaller avalanches were
observed in thick timber in the Sunshine area. The average crown depth
was 40 cm and the sliding layer was the Feb 12 surface hoar. In addition
to the natural activity there has been 8 reported skier triggered avalanches
throughout the region in the past 48 hours.

This surface hoar problem will continue
for some time into the future. Now is the time for very conservative decision
making.
