Observation: Turnagain

Location: Tincan - Alpine

Route & General Observations

Toured up to the alpine on Tincan, on what was supposed to be a sunny day, to take advantage of more moderate terrain choices in light of the persistent slab instability. Skinned the standard trail to Common Bowl. In the AM everyone was sticking to the low angles but by late afternoon many were looking for the persistent slab in all the right places.

Observer Comments

We had one collapse in the alpine @ ~2900' on a low angle slope as well as a small, fairly insignificant slab release (running on wind crust) on the top of CFR when pushed with skis.

Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.

Partly to mostly cloudy all day.
1000' @10:30 - 20 degrees calm
2300' @ 14:00 - low 20's light wind

Snow surface

1000' - 2"-3" of powder over a "mostly" supportable rain crust
1800' - 2"-3" of powder on top of a breakable rain crust
~2100' - 2"-3" of powder over a dense layer of storm snow


only did hand pits and found pits in the trees were coming off on what looked like the near surface facets under the recent storm snow but have to note the slab is thick and dense so hard to really isolate. At higher elevations into the alpine the couple of pits we did showed failing on buried surface hoar under the recent storm snow or a combo with the facets.
