First - My best wishs that you are alive and safe and that your wife can come on this forum and defend you rather than grieve for your death.
Both of you are taking this keyboard beating very well, continue to take it and be thankfull you are able to learn from it.
Second - I know that hill extremely well (See my Pic) I call it my "Death Hill". I have been stuck on it twice, the last time in 20012002 (see pic), thats me in the middle, I will never hit that slope again. Even tho you have never seen it slide in your numerous times there, I have seen it slide, and the after affects of slides on it MULTIPLE times. It is at the end of a 2mile valley that does nothing but wind load this point before it drops down into another dream valley of hills and mountains.
This is what I consider my favorite riding area of all, and I have no problem telling you its exact location in hopes that people riding there know it has an extreme avalanche danger as does everywhere in the West. It is out of the Smiths Fork area south of Afton, at a local place we call the "Terraces". It is the most avy prone perfect setup I know of for this to happen. It gets the wind and snow loaded from the complete valley.
And years ago I made the mistakes you made even tho I am very experienced and know how to read the snow and conditions. When I was stuck on it, I literally threw up, since while digging out I could hear under me "whump, whump" as the hill was getting ready to claim me. This one instance is what changed my hill banging exploits forever. I also get the biggest rush out of highmarking the big stuff but I now go frantic when I look at a hill.
The only advice I can give to everyone is:
YES, it can happen to you, ANYWHERE, educate yourself, cut snow holes to check, and insist your riding partners are as prepared as you, equipment and knowledge wise.
My final piece of advice is, learn how to say: "Nope I will pass on that hill."
God bless you for your courage to post this video and take the onslaught you are getting, continue to take it and answer these comments without debate nor defense, you could be cold, buried and dead.
My sincere regards, SLIM.
