Avalanche: Turnagain
Location: Tincan
Standard Tincan uptrack to tree line. Surprisingly good skiing up at tree line, but hazardous avalanche conditions abound.
Avalanche Details
3 D1-D2 soft slab avalanches were remote triggered by skiers descending the low angle uptrack of Common Bowl.
Obvious signs of instability
| Recent Avalanches? | Yes |
| Collapsing (Whumphing)? | Yes |
| Cracking (Shooting cracks)? | Yes |
Observer Comments
Remote triggered avalanches, numerous whumpfs, cracking and collapsing around skis.
Weather
Temps in the low to mid 20's, calm wind, clear skis.
Snow surface
12-16" of soft, settled powder. Intact surface hoar ranging from 1 mm to 3 mm that was widely distributed on all aspects up to 2000 ft elevation (highest point of tour).
Snowpack
Dug two pits at tree line. Both pits showed similar structure, with HS = 70 cm, ~40 cm F new snow over ~15 cm 4F rounding facets over ~15 cm P basal ice. S aspect pit test results: CT 13 at the basal ice / rounding facet interface. CT 15 at the new snow / rounding facet interface. ECTP13 SC at the new snow / rounding facet interface. NW aspect pit test results: ECTP12 at the new snow / rounding facet interface.
