Watch for windslabs as you enter open areas near treeline and above. Ice climbers may find windslabs developing at lower elevations when the Yoho Blow pushes through. Dress warm.
Avalanche Problem 1: Wind Slabs




Avalanche Problem 2: Loose Dry




Climbers in steep gullies be prepared for spindrift and loose snow running down the climb. Put in lots of ice screws. Any avalanches will likely be small, but could knock you off your feet.
- Be cautious of sluffing in steep terrain, particularly where the debris flows into terrain traps.
