Students triggered avalanches on test slopes around 1,300' on the Sunburst uptrack. The avalanches were small and happening only on 35 degree and over terrain. These were on slopes that were wind loaded with the recent snow. No remote triggers.
Recent Avalanches? | Yes |
Collapsing (Whumphing)? | No |
Cracking (Shooting cracks)? | Yes |
Wind loading was happening on west, southwest aspects.
There was snow accumulating throughout the day. Precip rates were S1 to S2. Temp at 2016' was -2C at 14:02. Freezing line later in the day seemed to be around 400' Winds were not strong but blew generally out of the east.
8" of new snow in non wind loaded areas. Good skiing above 1500' at Tincan
Dug 5 pits on Tincan uptrack at 2016'. Generally all ECTX, but one ECTP21 on the 1/21 MLK BSH. The BSH was easily visible. Other students dug at 1300' on Tincan Backdoor and Sunburst and had no significant results in pits. New snow did not seem to have a significant loading effect on the 1/21 BSH layer, although the layer was easily visible in the higher pits.
