200 foot natural arch in Afghanistan (Bamiyan) one of world's largest

A natural stone arch has stood for millions of years in the highlands of Afghanistan. But it wasn’t until recently that WCS researchers stumbled upon the special structure. Spanning almost 211 feet across its base, the natural bridge now holds the title of the 12th largest of its kind. Sorry, Outlaw Arch in Utah’s Dinosaur National Monument, this pushes you to number 13.

Wildlife Conservation Society scientists working in Afghanistan recently discovered one of the largest natural stone arches in the world.
