Prehistoric India to 1000 B.C. c9.10

c9.10

In the geological deposits of the lower slopes of the Himalayas of the Kashmir and Punjab region it has been possible to trace a succession of glacial periods, each indicated by typical products of glacial action. These in turn can be related to the structure of the river valleys in the Rawalpindi area, where terraces have been formed by the flow of the river cutting into the detritus brought down in an earlier phase. These problems of glacial geology are complex, and here, without involving the reader in a discussion of its difficulties, one can do no more than stress this complexity. But the combined evidence from glacial phenomena and river-terraces in Northern India suggests that there were in Pleistocene times five glacial periods (‘Ice Ages’) separated by interglacials in that area.
