It is difficult to visualize here just how deep this crevasse went past my boot. If you are interested in a different perspective; please see this image now in the pending gallery-

Thanks Christina, it was a lot of fun going down in that crevasse (we were doing rescue practice). I'd be pretty small from this perspective if I were at the bottom, as it was around 100 feet deep or so- a big one. If you fell into this and didn't die from the impact, you might soon suffocate from being tightly wedged in and unable to fill your lungs, or surviving all that the ice would rapidly suck all the heat out of your body. Probably best to not fall in a crevasse :-)
