Until 1992, the exact height of the mountain was not known with certainty and was given from 5,959 metres to 6,020 (19,551 to 19,849 ft) metres. In 1992 an expedition to the summit used GPS and fixed the elevation at 5,959 metres (19,551 ft); however a recent measurement taken twice from a plane showed the mountain reaching 5,966 metres. This new measurement has not been officially confirmed or recognized. Though the mountain is still growing due to tectonic uplifting, one reason postulated for the additional seven metres was an increase in snow and ice build-up.Mt.
