More detailed information about the avalanche: 

Triggered a small slab when dropping in off of ridge into very obviously windloaded area.  1st rider was able to escape to the side, second skier triggered another small piece of slab, but also skied away without incident.  This movement was expected and prepared for, but could have swept us into trees and rocks had we not been careful.
