Observation: Turnagain
Location: Tincan Trees North bowl below CFR
Toured and skied Tincan off of the normal uptrack and in the trees to the north near the base of CFR. We encountered debris from a large avalanche (D2+, 2.5?) that looked like it had started at about the 2600 foot level and ran down to the approx. 1900 foot level. Debris ran a surprisingly long distance over low angle terrain. It is possible it could have started higher up on CFR but visibility was poor and the debris was getting covered in new snow. It is most likely the slide occurred the previous night since we did not observe it on the previous day.
Obvious signs of instability
Observer Comments
Other than this avalanche and numerous small slides off of the corniced ridge there were no obvious signs.
Weather
Temps hovered around 32 all day at elevations between 2300 ft and 1500 ft. It was snowing most of the day with winds light but seeming to pick up on the ridges in the afternoon. Visibility was very poor most of the day.
Snow surface
1100' 1" new snow over frozen breakable rain crust
1800' 3-4' new snow over a variable crust (punchy and breakable in various areas)
2300' 5-6" new snow over supportable crust
Snowpack
Did not dig any pits or stability tests.
Treeline - 5-6 inches new snow over a supportable rain crust with wet snow underneath.
Mid-Debris pile where it started running along the trees.
