Wind slabs are likely present on lee features at all elevations and may remain reactive to human triggers on Sunday.
Whumpfing, cracking, and hollow sounds are all signs of instability that should cause you to back off into lower angle or less wind-loaded terrain.

No new avalanches were reported on Friday. However, our field team did report significant cracking on features that have been loaded by the wind. Whumpfing, cracking, and hollow sounds are all signs of instability that should cause you to back off into lower angle or less wind-loaded terrain.
On Thursday, explosives avalanche control between Carcross and Fraser produced a couple of size 2 windslab avalanches. These avalanches were on east and southeast aspects just above treeline.
10-15 cm of recent snow has been hammered by strong southwest winds. Expect wind-affected surfaces on all but the most sheltered north aspects.

This overlies a hard crust that extends up to at least 1200 m on solar aspects. Below this, the mid-pack is generally well-settled and strong in most areas.
Weak facets (sugary snow) exist at the base of the snowpack, especially in more shallow snowpack areas such as the Inland areas.
