Along the course of the now-dry Ghaggar-Hakra River system in today's India and Pakistan are scattered settlements of the Indus civilization. At a meeting last week, three independent teams offered preliminary evidence that the Ghaggar-Hakra was at most a modest seasonal stream during and after the Indus flourished from 2500 B.C.E. to 1900 B.C.E. The findings puzzle and intrigue archaeologists. If the river was dry or only seasonal, it may prompt a re-evaluation of how Indus peoples acquired water for agriculture.
