Yale North India Expedition


ALL the members of the expedition of the Yale North India Expedition 1932-33, under the leadership of Dr. H. de Terra, having returned to Yale University more than a year ago, it is now possible to give a brief preliminary account of some of the results of the field work achieved. In our geographical studies we were fortunate in securing the services of the distinguished Indian topographer, Khan Sahib Afraz Cul Khan, who surveyed 4,600 square miles of imperfectly mapped country on the western borders of Tibet. Dr. de Terra, using this new map in conjunction with his geological studies, has been able to recognise the eastern continuation of the Karakorum on to the ‘Tibetan plateau’. The orographic axis of the range undergoes a bend from north-west-south-east to west-east, so that the Karakorum clearly fails to make its supposed connexion with the Trans-himalaya. The re-entrant, clearly marked in all the component ranges of the Karakorum, is represented throughout the whole of the mountain belt between the Ganges and Central Asia, and corresponds to that of the Gondwanaland mass.
