Avalanche: Turnagain

Location: Tincan trees

Route & General Observations

AGC Private course took Tincan Backdoor route from Center Ridge Parking lot. Skin track from yesterday had already blown in. Light wind pressed texture and soft baby sastrugi even starting from the parking lot. Clear weather in the morning allowed us to get eyes on all surrounding peaks and no natural avalanches were noted (disappointing that we didn’t get the ole Chugach Crush and Flush). Later, we were able to get up high enough to notice a pretty large natural avalanche in Hippy Bowl that was recent.

Avalanche Details

We don't have many details, but took a photo. Our turn around point due to flat light didn't get close enough for further details, but judging from all we know about the snowpack and the appearance of the crown is that the weak layer were the infamous facets above the halloween crust.

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

Clear and 12 degrees at 9:30 a.m. Clouds quickly moved in making light flat and by 3:00, temp had risen to 22 degrees and snow was lightly falling as we left. 20" of new snow had settled to about 12".

Snow surface

Settled snow was wind pressed with soft sastrugi on the surface and a small wind skin. Lots of new wind features as we looked around.


Dug six pits W-SW at 2000' on Tincan
HS varied between 150-220 cms, Ski pen: 25 cms, boot pen: 55 cms
No notable results on all of our ECTs besides that we could get failure on overdrive after 30 taps propagating on the facets above the halloween crust. There was also a tiny layer of near surface facets about 45 down between the last two storms that occasionally reacted but without propagation.
