The scariest thing about falling into a crevasse is if you know how they kill people. They’re generally wider at the top and taper down so falling in doesn’t kill you most of the time. You get wedged in when it’s not wide enough for you anymore and your body heat slowly melts the ice and you slip millimetre by millimetre deeper into the gap. Every breath let’s you slip a little further until you can’t expand your lungs enough to breathe and you suffocate. Whole process takes hours and hours.
