Transceiver or no, the releases occuring on that layer in the Utah BC will smoke you right now, no chance of survival.
If you read the avalanche forecasts from the days leading up to this tragedy, the cagey veterans were nervous, and there was plenty of documentation of massive, and in some cases, unprecedented releases occuring.
I have no comment about that gate at The Canyons, but making it so a skin is required might change the typical user of that out-of-bounds area. I hear it is typically people who have no idea about the difference between out-of-bounds and controlled in-bounds, yet go to the resort specifically to ski/board this area. I certainly would not be going there on any day, specifically because I would not want to ski with people above me who have no concept of b.c. etiquette. I wonder what they will do. I would guess status quo will not be the answer chosen. At the very least, I would think the resort would stop promoting it as a reason to visit (not sure if they do anyway, but it seems the word is certainly out there).
