Prophet 130, ouch.  I lost a ski in 50cms of fresh once at Kicking Horse.  
First run, too.  
I wanted to commit suicide as I spent over 2 hours looking for it on a 45-deg pitch in hip deep.
That is the definition of skier hell.  
Everyone else going down was hooting and hollering.
Found it near hour #3 when a dude like 120m down creamed my ski.  It'd actually slid under the snow...literally impossible to find.  
I had hand packed a football field at that point.
Sucked large, but I got the ski.
Good luck, dood.
