A hard crust with surface hoar or facets overtop is buried 35 to 110 cm deep. Wind slabs could step down to this layer, creating larger than expected avalanches.
New snow will be falling on a crust that extends to the mountain top in many places.
Check the bond between new snow and the crust before committing yourself to avalanche terrain.
