Observations from the past two days in the Musical Bumps and Lower Disease/Chuting Gallery: Snow generally right side up after the past two days at treeline, with some wet over lower density at the 180116 interface. Lots of wet underlying the past two day's snow BTL, with right side up and dry and light on top at 1700m and up. Ski pen in trees up to 45cm at 1700m and deeper in the Chuting Gallery. Top of Gallery shows lots of wind deposition and wind slabs. Ski cuts on convexities producing loose dry in trees and windslabs to 50cm deep near treeline. Best riding in tight and steep trees. Watch for windfalls covered by latest storm snow...we had one rider faceplant right next to a stump that would have done more than ruin his day...treewells will be coming back into concern near treeline as well. Temps about back where they should be for good snow conditions...


From Mitch yesterday at Hanging Lake. Storm skiing without the wind in heavily-caked old growth forest. We found good stability from TL down. Older windslabs bonding to 180115 mfcr reasonably well and only minor whumpfing. Skied from 900m-1700m on Sw through S to E asp. Significant accumulations of right side up from 1250m up. Open creeks still a caution. Snowbanks my be 2.5m above creek and some bridges still suspect.
