| Cracking (Shooting cracks)? | Yes |
Observation: Turnagain
Location: Tincan Treeline
10:30-Ascended standard approach track with my partner towards upper-treeline to conduct instability tests of recent snowfall. Descent took nearly as long as ascent due to waist deep, dry snowfall. Light, consistent northerly winds pursued throughout the entire day with S1-S2 precipitation with 20-25°F(M), no observed wind depositing. Pockets of blue sky appeared over Sunburst and the Valley Fog lifted around 2:00pm. Gore-Tex is a wonderful innovation.
