the policy of the great trigonometrical survey was to use local names for mountains when possible. k1 had the local name of masherbrum which was soon used. k2, however, appeared not to have a local name. this may have been due to its remoteness. it is not visible from askole, the last village to the south, or from the nearest village to the north. it is believed few local people would have gone to where it could be seen. the name "chogori", from two balti words, "chhogo" ("big") and "ri" ("mountain") (چھوغوری) has been suggested as a local name. there is not much evidence for its widespread use, however. it may have been invented by western explorers. it does form the basis for the name "qogir" () which the chinese government uses as the official name of the mountain.
