Weak layers of faceted snow exist in the top meter of the snowpack on Northerly aspects. In my travels yesterday, I found these layers to be gaining strength and they didn't react to stability testing. Friday's storm dropped almost two inches of water on our snowpack and did not produce any avalanches. This is another good sign that these layers have gained some strength. With that said, I still recommend digging down and assessing these weak layers if you are choosing to travel on Northerly facing slopes. These weak layers are not widespread, you may find them on some slopes and not on others.
This snow pit is on a NW facing slope at 11,080 ft. You can see the 2/22 interface down 53cm and the 2/14 interface down 69cm. You'll want to look for and evaluate these two layers if you are getting into slopes steeper than 30 degrees today.
