A massive stone archway, one of the largest natural bridges in the world, has been discovered in a remote corner of Afghanistan.

The dramatic arch spans more than 210 feet (64 meters), edging out Utah's Outlaw Arch in Dinosaur National Monument to become the 12th-largest arch on Earth.

The recently discovered Hazarchishma Natural Bridge is also nearly 10,000 feet (3,000 m) above sea level, making it one of the highest large natural bridges in the world.

Researchers from the Wildlife Conservation Society stumbled across the geological colossus in late 2010 while conducting wildlife surveys along Afghanistan's Bamyan plateau, home to ibex and urial wild sheep.

"It's one of the most spectacular discoveries ever made in this region," said Joe Walston, director of the Wildlife Conservation Society's Asia Program. "The arch is emblematic of the natural marvels that still await discovery in Afghanistan."

Consisting of rock layers formed between the Jurassic Period (200 million to 145 million years ago) and the more recent Eocene Epoch (55 million to 34 million years ago), the Hazarchishma Natural Bridge, named for a nearby village, was carved over millennia by the once flowing waters of the now-dry Jawzari Canyon.

"Afghanistan has taken great strides in initiating programs to preserve the country's most beautiful wild places as well as conserve its natural resources," said Peter Zahler, deputy director for the WCS Asia Program. "This newfound marvel adds to the country's growing list of natural wonders and economic assets."

On the one hand it's cool that things are still waiting to be discovered, on the other hand Afghanistan was a hippy hiker destination in the 1970's. This thing could have been documented so much sooner if not for all the douchebaggery. :roll:

Sorry Scott. :lol8:


First it (Outlaw) was #9, then it dropped to #13, then rose to #12 and now it's back down to #13. Who knows what it will be tomorrow?:haha:

Anyway, that one in Afganistan is a pretty cool looking arch.

According to Wikipedia, Rainbow Bridge was reduced by 41' when measured with a laser in 2007. I guess I missed that news, but a reduction of 41?! That's huge! How could they have been that off? It's not like Rainbow is slanted and the 1974 measurement of 275 could be fudged at an angle or something. Measuring to the outside of the span? Strange.

Thanks for posting this. It was very interesting.

Probably so. The pervious measurement was very old and there was no criteria for measuring arches/bridges until recently.
