Avalanche: Turnagain
Location: Tincan
Tour up to the Tincan Ridge (to 3,300′), common approach.
Avalanche Details
Countless glide cracks and avalanches all over Tincan and other terrain around Turnagain Pass. This was seen on every aspect near and below 3,000'. It is hard to find a slope that doesn't have a glide avalanche or a glide crack.
These have been releasing for weeks now, but it seems the past week of warm/wet weather has induced an uptick.
Obvious signs of instability
| Recent Avalanches? | Yes |
| Collapsing (Whumphing)? | No |
| Cracking (Shooting cracks)? | No |
Observer Comments
Only sign of instability was the glide cracks. Easy to see and avoid being under them.
Weather
In and out fog/low clouds with some sunshine!
Temps near 30F along ridge.
Winds mostly calm, light easterly breeze at times.
Snow surface
Patchy wet snow and ground from parking lot transitioning to breakable rain crust over softer wet snow from 1,500-2,500'. Not fun skiing in this elevation band...
6-8" of nice new dense moist snow above 2,500' to our high point at 3,300'.
Snowpack
Wet snowpack through and through below 2,500'.
Snow depth at 2,500' is around 3'.
We dug a pit at 3,200' between Common and Hippy Bowls, SW facing.
Snow depth at 3,200' between 4-5'.
ECTX - could not find a weakness in the pack. It's quite moist with some melt freeze layers near the base and some wet layers near the surface.
Older glide avalanche in Tincan Common Bowl. Snow has fallen on the bed surface in the past day or more.
Side view of the same glide on Tincan Common.
Wider view of the the SW face of Tincan, under Common Bowl. Runnels and glides everywhere!
Snowpack at 3,200' - no weak layers seen, moist snowpack. Around 4' snow depth at the pit.
And more glide avalanches and some cracks that have not slid - this is below Common Bowl on Tincan under the CFR ridge near treeline.
Former CNFAIC forecaster Heather Thamm tries to see some humor in the horrific breakable rain crust on the surface at 2,000'...
A look at more glide cracks - these are on Hamburger Hill along the common up route.
Several small water crossings to navigate down low.
