The hardslab that has formed along most exposed ridges is becoming much more sensitive with the continuing strong SW wind. I triggered this HS in Runaway Cliff above Sundance today while just tickling the slope right along the ridgeline. It propagated about 300' back to the east and pulled out a portion of the ridgeline that I had just used on the ascent. The crown averaged 2' but in places it was close to 4' deep. In one portion of the crown I found the rime crust at the failure layer but the majority of the weak layer was simply low density stellars below a 1F windslab.
