Still seeing fresh avalanches on north and east aspects. Able to find some wind slab that will crack even well off the ridge lines

Problem #1 Comments

The deep slab possibility is still present. Pole probing reveals poor snow pack buried down in the snow. However the slab on top is strong but still a slab.

as seen today a north facing portion of a ridge coming off of gobblers knob that had wind sculpted snow around it released within the last 24 hours.

We found wind slab formed well off the ridge in the Wilson Glade as well.

Comments

Chose to ski a known repeater slide path today that had only new snow on it and a moderate slope angle. I personally would not be exposing myself to steeper terrain with the present snow pack. Besides the skiing is fun on safe terrain.

Also noted but of little surprise that the Alexander/Baker Spring east facing ridge has avalanched (east bowl) as well.

Seeing all of these slides on steeper terrain you have to rate the danger as considerable but slope angel dependent. The trick is knowing the critical angel.

Attached pic of wind slab that pulled out.
