AVALANCHE OBSERVATIONS
 No. Location Date Size Type Trigger Aspect Elevation Comments
 1 Smiley Ck - Abes Armchair Yesterday 2 U N E 8700 E/SE aspect, crown was about 100' below ridgetop,fresh slide. The grey bed surface and general appearance indicate it failed on Thanksgiving crust or December facets. Probably failed yesterday/last night/early this morning. Trigger was most likely natural but could have been remotely triggered yesterday or this morning and I couldn't see the tracks?
 1 Titus Peak Yesterday 3 U N NE 10000 Cardozo observation. Crown appeared to be over 5 feet tall.
 Comments: A local professional (Cardozo) observed a large D3 slide that occurred around the same time on the N/NE face of Titus Peak, above treeline near 10,000 ft elevation.
