The book of the 1986 British expedition gives the mountain's height as and states that Gangkhar Puensum is completely inside Bhutan, whereas the nearby Kula Kangri is completely inside Tibet. Kula Kangri, 7,554 metres, is a separate mountain 30 km to the northeast which was first climbed in 1986. It is variously mapped and described as being in Tibet or Bhutan.
