This might be the most intelligent post and person to post on this dentist board. And the advice therein might be the most important. It will save a life.Wow. Sunday was one of the most bizarre days I've been involved with here in the Wasatch since my arrival in 89'. I understand some of it but we'll be talking about that day for a long time to come.
Just want to add a couple of things.
First, a note on persistent weak layers. These are facets or surface hoar that get buried and produce activity through a number of storms. Faceted weak layers especially, are the cause of the majority of injuries and fatalities here in Utah. You cannot screw around with persistent weak layers as perhaps you can with a new snow only instability. You need to leave the slopes with facets alone until a decent storm comes through and no avalanches occur. The ECT is the best test that I've seen for this. After using it for a few years I think that when propagation occurs in a test it coincides pretty well with avalanche activity. So, when propagation occurs and you've heard the words "facets" or "persistent weak layer", it's time to leave it alone for a bit. As for right now, while the buried junk doesn't cover a huge chunk of the terrain if you consider all aspects above say 7000 feet, I wouldn't call it "isolated" because it appears to be present in ALL northerly facing terrain above around 9500'. While I like steep pow as much as the next "jong", I'll wait till another decent storm comes through with no avalanche activity after it, then start thinking about the following storm. I'm trying to be in it for the long haul.
Second, it is so helpful if you submit an observation to the UAC if you see or trigger an avalanche. We don't always have time to sift through the forums for these. I set up a database a few years ago and we have fields for size, trigger, aspect, etc. This makes the database quite "searchable" where people can query it to look at trends and whatnot. Like, show me all the human triggered avalanches on NE facing slopes above 9500'. After a couple of seasons we are starting to have a nice dataset to work with. I plan on setting up this search method so the public can use it soon.
Thanks a bunch,

Great read.
