Wind Slabs

Wind slabs are present in the alpine on lee and cross-loaded features. Isolated thin slabs are also found on South aspects due to recent Northerly winds. Carefully evaluate the bond between these slabs and the crusts beneath.
Assess start zones carefully and use safe travel techniques.>Avoid lee and cross-loaded terrain near ridge crests.>Travel early on frozen crusts before the heat of the day.>
