Sometimes it just happens. Each year I get a copy of Accidents in North American Mountaineering and read it from cover to cover. Read enough of these stories over the years and you'll see that even the experienced make blunders. There are statistical tables in the back of each issue with categories such as terrain, ascent or descent, immediate cause, contributory causes, age of individuals, month of year, type of injury, and experience level. For instance, in the USA between 1951 and 2008 there were 2039 rescues/calls for assistance for people deemed experienced. I agree with Salty and Bulldog - always gaps to be filled in with press reporting.
