Highest unclimbed mountain in the world.

Most sources indicate that Gangkhar Puensum (7,570 meters (24,840 ft)) in Bhutan or on the Bhutan–China border is the tallest mountain in the world that has yet to be fully summited. Gangkhar Puensum has been off limits to climbers since 1994 when Bhutan prohibited all mountaineering above 6,000 m (20,000 ft) due to spiritual/religious beliefs, and since 2003 mountaineering has been forbidden completely.
