Wind Slabs
Wind slabs exist in the alpine and some tree line locations that may be possible to trigger in steep terrain. They are sitting on a variety of surfaces including old wind effect, surface hoar, sun crusts and facets.
- Be careful with wind loaded pockets, especially near ridge crests and roll-overs.
- Watch for surface cracking and stiffer surface layers of snow.
