This is a great test. As with everything in avalanche safety it's not a magic bullet that covers everything. It is a great tool in your arsenal. I also know that this test was primarily developed in Continental and Intermountain climates. I'd be interested to see how this works for you Maritime guys. So if you haven't tried it, give it a go and let me know how it works for you.
It's definitely replaced the Rutschblock test for me in most instances. Mostly because it's a much quicker test to set up, so I easily can do it in several representative spots in the time it takes me to do a Rutschblock.
This is the most decent video I have found on it. Last year in my class we had a great (scary) result doing the ECT. It propagated and shot out. gapoostQuality 1 shear with lots of energy. It popped the eyes of the class which was great. Love it when you can demonstrate this sort of stuff. Bonus points for this one actually being kind of fun to do.
Hopefully this is new to a few peeps. Give it a try, let me know what you think.
If anyone knows of a better video, please link it up.
good vids, great test. one thing that bothers me in the vids is how these guys keep referring to faceted layers/hoar frost/propagations/etc. as 'nice' 'great' 'sweet' whatever. they are none of that. they're nasty, shitty, scary, deadly, etc... other than that - good shit.
good video's and tips! we in the NW don't get to many funky layers.. but the HOAR can exist.
Yeah, for sure. I am amazed at the stability in the PNW. When it goes though, it sure seems to like to go big. Still, I think there are times when you get a persistent weak layer, especially around storm cycles. It would be interesting to give this a try during times of instability in your region and see how it works for you.
