Gangkhar Puensum is world's highest unclimbed mountain

Everest, K2, Cho Oyu are some of the world's highest mountains and they have all been climbed some decades ago.

But smack dab on the border of Bhutan and Tibet in Central Asia is Gangkhar Puensum, the 40th highest peak in the world and believe it or not, it has never been climbed.

This is partly due to geography disputes. Some maps place this towering peak fully in Bhutan while others say its on the border. Because of this and the spiritual beliefs of the Bhutanese, mountaineering in general has been kind of a no-no.

According to amusingplanet.com, Bhutan opened itself to commercial climbing in 1983 so many tried to tackle the nearly 25,000 square foot high mountain and all of them failed.

The decision to keep the peak open to climbers ended quickly in 2004 and a ban was placed on climbing throughout the entire country of Bhutan. It looks like Gangkhar Puensum will continue to hang onto the record for highest unclimbed mountain.
