   “1896, James Edward Todd, The Moraines of the Missouri Coteau, and Their Attendant Deposits, US Geological Survey, Bulletin No. 144, page 47, This fact is suggestive in connection with the question whether the moraines mark different epochs of the ice age or different stages in the recession of the ice of one epoch. This moraine, like the previous ones, influenced the drainage of the country. Several streams have evidently been located or directed by the influence of this moraine.”

   “Prof. Dainelli made a personal study of the lakes of the Upper Indus lying between its confluence with the Gilgit on the west and the plains of Kashmir on the east. From this district he cites fifty lakes and groups of lakes. Many of these are moraine-dammed, but some of the larger ones, as the Satpor Tso, the Tso Moriri, the Chiun Tso, and the group of lakes associated with the Pángong Tso, he considers to have originated by glacial excavation.”
