Lizard-Flathead

Watch for changing conditions as you gain elevation, small rider triggerable wind slabs may still be found at treeline and above.

Avalanche activity has tapered off since the past weekend’s storm. Explosive control on Monday and Tuesday produced size 1.5 wind slab avalanches. These slabs may still be triggerable by riders.

Wind affected snow may be found in exposed terrain at higher elevations.

20 to 30 cm of snow sits over a mix of crusts, surface hoar in wind-sheltered terrain, and hard wind-affected surfaces. Reports suggest the recent snow is bonding well with the layers below.

The middle of the snowpack is generally expected to be well-settled and stable. Total snow depths vary from 100 to 150 cm at treeline.

• Closely monitor how the new snow is bonding to the old surface.
• Be careful as you transition into wind-affected terrain.
