Glacier

Increased wind on Friday will create wind slabs in exposed terrain.

Use caution near ridge top and on leeward slopes.

• We are confident due to a stable weather pattern.

No notable natural avalanches have been observed over the last few days in Glacier park. See MIN report for small, human triggered wind slab on Wednesday.

Near neighbours have been reporting cornice failures this week, both natural and explosive triggered.

A widespread, natural avalanche cycle occurred up to size 4.0 on Mar 19-20 during the atmospheric river. Check out pics from this exceptional avalanche cycle in the MIN Reports.

A widespread sun crust can be found near the surface on soar aspects. Sheltered polar alpine terrain holds dry, loose snow sitting over a firm crust. Wind slabs might be lingering in exposed terrain.

Large cornices can found on ridgetops.

A series of crusts formed in March are present down 50-150 cm.

Travel can be challenging below treeline with frozen tree bombs and huge avalanche debris from the mid-March atmospheric river.

Rising temps and flurries.

• Be careful as you transition into wind-affected terrain.
• Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
