description
Wind slabs on top of wind slabs exist at upper-mid to upper elevations, and snow has been deposited further down slope than is usual. The danger will be most acute on upper elevation slopes that face N-NE-E, but with winds of this intensity cross loading has been a factor and you may encounter wind slabs on all aspects. Suspect smooth rounded pillows and look for cracking in the snow surface. Avoid slopes steeper than about 30 degrees that have recent deposits of wind drifted snow. |

description
Buried layers of weak faceted snow, sometimes associated with a crust, can be found on most aspects at mid and upper elevations. How reactive they are varies from slope to slope, and about the only way you can be certain is to dig down and test them. Steep, upper elevation, wind loaded slopes should be avoided. In these areas it is likely that a triggered wind slab will step down into a buried weak layer causing a deeper and more dangerous avalanche. Out of the wind zone, the danger will be less obvious and stability analysis will need to be performed on a slope by slope basis. |
