River Capture Happening Now! (- well almost)
The Guardian reports how the northerly flowing waters of the Slim River were diverted into the Alsek River which flows south. The diversion happened when water from the rapidly retreating Kakawulsh glacier eroded a channel to the Kaskawulsh River and eventually the Alsek. And all this happened in four days in May last year.
