During the last glacial period, at around 50,000 B.C., a 5-cubic-meter boulder became wedged into a crevasse in Scandinavia, just southwest of the village of Lysebotn in western Norway.
The boulder is accessible to tourists, but be careful: There are no fences, and the abyss below is 984 meters deep.
