Snow Cover

Wet loose snow Wet Vått snødekke til topps på trolltind. Gravde ikke men klarte å trykke staven helt ned til bakken og så at det var mye vann i snøen. Går løssnøskred når man kjører brattere enn 30 grader.

Avalanche Observation

22. May 12:56 (+02:00) Wet loose-snow avalanche 2 - Medium Human triggered E-facing Avalanche release at 1222 masl and ended at 1067 masl Steep slope Observerer skred fra parkeringen. Skredet hadde blitt utløst etter vi gikk fra parkeringen og før vi kom tilbake. 1 skispor inn i skredet, 1 skispor ut av skredet, så har ikke varslet nødetater om skredet. På lang avstand ser det ut som str 3, men siden det er løssnøskred antar vi at det har volum som str 2.

Avalanche Activity

22. May. During the day (+02:00) Glide avalanche One (1). 3 - Large. Spontaneous release Isolated steep slopes. E, SE, SW. Above 1200 masl Så 1 str 3 og noen str 1-2 fra Trolltind. Vet ikke når skredene har gått. Så i tillegg glidesprekker flere steder.
