Watch this spectacular video of speedrider David Bozon skiing near the edge of a cliff in Charmonix, France, and then taking a leap off to ride the avalanche he just provoked.
This is pretty unbelievable. Richard Henriksen, a basejumper, fell off a steep rock cliff after his high bar collapsed yet he still somehow survived. Watch the video and wait until the very end, Henriksen and the whole setup both disappear and plunge to the ground.

St. Maurice's Abbey in Switzerland was built in a rather precarious place. Constructed in 515, the building stands tall against a steep cliff that is prone to rock slides. Damaging rock slides.
Verona Rupes is a huge cliff face located on Uranus's moon Miranda. It's the tallest cliff in the solar system, as much as twenty kilometers deep. If you jumped off it, you'd fall for twelve minutes...and you could still survive.
