What is "changabang"

Changabang is a mountain in the Garhwal Himalaya of Uttarakhand, India. It is part of a group of peaks that form the northeast wall of the Nanda Devi Sanctuary. It is a particularly steep and rocky peak, and all routes on it are serious undertakings. It has been the site of many significant climbs. It does not have a high topographic prominence, being slightly lower than its near neighbor Kalanka to the east, and lower than many other peaks in the immediate vicinity, but its steep rocky profile has made it a more attractive destination than its elevation would indicate.
