General Comments

We intentionally triggered this slab with a ski cut at the very top of the bowl.  Yesterdays dense slab is now a hard slab and therefore a little stubborn.  It also increases the potential to propagate longer distances.  This slide propagated very fast and quickly picked up speed.  It initially failed at the upper most layer of very weak facets now buried about two feet from the surface and then gouged much deeper as it moved.  Lots of brush and ground cover was exposed in the bed surface but I feel that there is still plenty of weak snow left over to worry about with future loads.

This slide ran almost full track with lots of speed and a sizable powder cloud.
