It is not a large slide. Large enough to bury a person though. Class 2 I believe is the definition of a slide large enough to bury a person.
Another old adage is "Q: What is the most dangerous type of avalance? A: The one you are caught in."
Size does matter, but if it is enough to kill you it is plenty dangerous. I know I certainly would not want to go for a ride in that.
I was actually more curious about the size of the slope in general.
