Hmmm...the link isn't working for me. However, I'm not surprised at the list you mentioned. Drowning and falls are both real possibilities where I live; many falls here will result into a long drop into a river or lake! I've sadly been on the wrong end of a few falls over the last few years so I'm extremely careful now, but the risk it always going to be there especially in the mountains.
