Avalanche Details
Both a natural avalanche and smaller remote triggered avalanche (2.5' deep, 50' wide, running 50') were seen today around 2,000' in the Tincan Trees. We also had reports of similar depth slabs on the steep rollovers in the trees.
Obvious signs of instability
| Recent Avalanches? | Yes |
| Collapsing (Whumphing)? | No |
| Cracking (Shooting cracks)? | No |
Observer Comments
Recent avalanches, heavy snowfall, strong winds. Rain below 1,500'.
Weather
STORM DAY. Snowing 1"/hour roughly 1500' and above. Rain fluctuating between 1,000' and 1500'. Winds light with strong gusts from the NE in the trees. Temps 36 degrees at 1,000', near 30F at 2,000'.
Snow surface
2 feet of new medium density snow above 1,500' and wet new snow below this.
Snowpack
2,000 feet: 2 feet of new moist snow sitting on ~5mm buried surface hoar with 3-4" of near surface facets below. Under the facets was a crust ~1" thick. See pit profile.
We talked to several other skiers in the area and collapsing (whumphing) was reported along with several other 'rolls' in the tincan trees avalanching. All avalanches were believed to be composed of the new 2-3' of storm snow. Bonding with the old snow surface was poor today in general. There were some reports of small slopes as well being stubborn and did not avalanche.
One natural avalanche (looker's left) and one remotely triggered avalanche (looker's right) near the Tincan common uptrack.
