Which mountain is taller, Lupghar Sar or Gyachung Kang?
Gyachung Kang:  As the fifteenth-highest peak in the world, it is also the highest peak that is not eight thousand metres tall; hence it is far less well-known than the lowest of the eight-thousanders, which are only about 100 m (328 ft) higher. Lupghar Sar: Lupghar Sar is 109th on the list of world tallest mountains.
