One report of a skier accidental size 1.5 from an East aspect in Boulder creek that released in some fresh wind slab that was about 20 cms deep and ran about 150 metres.

Snowpack Summary

Thin new wind slabs are developing due to West-Northwest winds. These wind slabs may be sitting above recently developed surface hoar and surface facets in area where they were not stripped by the wind. Strong solar radiation may have developed sun crusts on solar aspects up to about 2000 metres. The mid pack is reported to be well settled without any layers of concern. Depth hoar and facets are reported near the ground in areas with a thin snow pack.
