I am reading this highly-rated book about avalanches and I was impressed by this sentence, in its beginning.
Over 25 percent of avalanche victims in the U.S. die from trauma from hitting trees and rocks on the way down (about 6 percent of avalanche victims in Europe and as many as 50 percent in Canada)
How can there be such a massive difference? 6 percent of people dying from trauma from hitting trees and rocks in Europe and 50 percent in Canada... with the US being about in the middle of that statistic.
The very first - quite rough - idea that comes to my mind is, there may be much more trees and rocks in the average Canadian ski route compared to European ones.
But, it sounds quite superficial. Still, those numbers differs too much; there must be some reason behind this spread. Does anyone knows what this reason is (or are)?
