Salmon do the upstream thing better than people... they even manage to get up waterfalls.
Albert Leichtfried and Markus Bendler climb waterfalls all over the world, by cheating... they wait until they are frozen. The waterfalls, not the climbers.
Hermann Erber was taking pictures of the dynamic duo, climbing this hundred meter high frozen falls in Japan, when the entire right side of the falls collapsed. Fortunately they were climbing the left side, and although the climb had to be aborted, they got down safely, probably changed underwear, and hiked out of there.
They went back a couple days later, but the temperature had risen, so they gave it up. Good move, I think.
