Continuously assess conditions and look for signs of instability as you move through terrain.
New snow amounts vary throughout the region and so do the surfaces it has fallen on.

Avalanche Summary
On Monday there were several small rider triggered dry loose avalanches reported.
On Sunday, southwest of Mcbride a small (size 1.5) wind slab was remotely triggered from 5 metres away with no involvement.
Snowpack Summary
5 to 15 cm of new snow has buried a variety of surfaces including surface hoar and facets in sheltered terrain, a crust on south and west facing slopes as well as old wind slab on exposed terrain.
The widespread crust buried in early February is near the surface on exposed alpine terrain and down up to 45 cm elsewhere. In many areas this crust has a layer of facets above.
