My partner & I were present on the day of the avalanche referenced above. It was a high hazard day as noted in the avalanche report. We were at the hairpin skiing a low angle treed run. We crossed the avalanche terrain in question one at a time to access the run. There were several recreational parties as well as Jeff Ward's guided party who was clearly behind us. Everyone was concentrated in the same area. Breaking trail was very difficult & this was all done by recreational skiers. Mr. Ward's party followed our skin track. As he was skinning up our trail for his first run, we skied by him on our first run down.
On our second run, one of the recreational skiers, drunk on powder, was skinning up on his own, he got ahead of everyone, we didn't know his plan. He made a bad choice & entered the trigger point at the head of the avalanche zone. He triggered an avalanche that swept to the bottom & partially buried Mr. Ward's 2 clients. One of his clients lost their ski which was not retrieved. The skier who triggered the avalanche hurt his ankle & also lost a ski, which was not retrieved. The recreational skiers helped him get to his sled. Fortunately no one was hurt or died that day. There is a definite danger placing yourself under parties skiing above. I hope we can all learn from this.

Here's another "tall" ECT performed by an avy pro.
Looks like an ECT 30 Q1 at 1.55 m to me.
These guys seem to be using it deeper than the recommended 1M!!!

Would you ski after getting that result with no naturals or any other observed instability and strengthening upper snowpack???

That's a good question, I'm still learning the ECT test so help me out here but isn't the ECT for determining propagation not failure? In this case, I'd say that one propagated easily which would be an indicator of instability so I would not ski that slope. A more difficult question for me would be if that ECT test propagated only half way on the 30th blow...

Out of town for a week. I removed a few posts here that weren't on topic for the ECT. Freeski, you and Jeff need to have a more clearly defined agreement than you appear to have had if you're going to post your PMs to each other. If you want to talk about that, PM me, but please don't use this thread for it.
