Observed one natural avalanche on an easterly aspect around 9,000'.  (approx size:  40cms deep, 100' wide.  Steep, rocky terrain).  It looked to have occurred late last night or this morning.  
 
Lots of collapsing and cracking.
 
Also one remotely triggered slide in Pebble Creek today as well! (photo attached) Triggered it from about 40' away, on lower angled terrain.  Adjacent profile...(HS 137, ECTV @93, on 2mm facets).  It was on a wind protected, north aspect, around 8,800'.  The crown was about 45cms deep, and 25' wide.
