One of the world's largest natural stone arches was discovered in a remote corner of Afghanistan. It measures more than 210 feet in width and is more than 10,000 feet above sea level. This is the 12th largest natural bridge in the world. The arch includes rock from the Jurassic period, and the Eocene Epoch. The stone was discovered in late 2010, but wasn't until recently that the stone was measured, and it was determined to be the 12th largest.
