this is pretty darn interesting. i've never given much thought to mountain climbing. i mean, you climb up, probably with a rope and you climb down. sometimes you fall down. so? you have to not be afraid of heights, but ... so?

well, after clicking on the little green boxes and seeing what is actually at person-level on these wide, flowing rivers of snow and ice, i am actually pretty intimidated. climbing is not the world for me. i mean, it takes energy and stamina. i mean, at first you think ... hmmm, so? but clicking on those little boxes is an eye-opener.

check it out. but only if you have at least half an hour to spend.
