Avalanche: Turnagain
Location: South Side of Tincan Proper
Skinned up normal uptrack, booted along the ridge to tag the proper summit, and as we booted back down to the common bowl to ski, we noticed a point release on the sun-baked south side of the ridge. It was big enough to knock someone off their feet, maybe large enough to bury someone. We were surprised at this, as the rest of the southerly aspects that we were travelling through felt quite solid, and we saw no other obvious signs of instability.
Avalanche Details
I don't know the exact slope angle, but it was steep, probably 40-60 degrees. We also didn't see the exact trigger, to see if it was caused near exposed rocks to warm it, but that would make sense.
Observer Comments
Didn't see anything besides this.
Weather
Sunny, 25-30 degrees, but felt super warm with the radiation. South wind 5mph. No new snow for more than a week.
Snow surface
hard wind crust, with pockets of sluff.
Snowpack
Performed an ECT on the north side of the ridge just above tincan common. Had to jump on it from above to get it to fail on the ground facets, for a slab ~3 feet thick.
The slide started somewhere in this area. We only saw the end of it, so didn't see exactly where it started.
