It is a dramatic range of steep rock and ice peaks with great local relief. However it is not as well known as other parts of the Himalaya since its highest peak, Bharanzar, or Sickle Moon, is only 6,574 m (21,568 ft) in elevation. One of its best-known peaks is Brammah I, 6,416 m (21,050 ft), climbed by Chris Bonington and Nick Estcourt in 1973.
