Gangkhar Puensum
7,570M in Bhutan
Gangkhar Puensum (also spelled Gangkar Punsum) is the highest mountain in Bhutan, commonly listed at 7,570 m, located on or near the Bhutan–Tibet border in the Lunana highlands (Lunana Gewog, Gasa District). It is widely reported as the highest unclimbed mountain in the world. Bhutan introduced successive mountaineering restrictions (including a ban on peaks above 6,000 m in 1994) and currently prohibits mountaineering, so summit attempts are not permitted from the Bhutan side.
