The summit of Gangkhar Puensum
This giant peak that overlooks Bhutan and China is the fortieth-tallest summit on Earth, reaching 7,500 metres (24,600 ft) above sea level. It is also the highest peak in the world that has never been reached, despite several failed attempts. Since 2003, it has been forbidden to climb it. The mountain’s name translates as White Peak of the Three Spiritual Brothers.
