Geochemical 'fingerprints' leave evidence that megafloods eroded steep gorge

[unable to retrieve full-text content]For the first time, scientists have direct geochemical evidence that the 150-mile long Tsangpo Gorge, possibly the world's deepest, was the conduit by which megafloods from glacial lakes, perhaps half the volume of Lake Erie, drained catastrophically through the Himalayas when their ice dams failed during the last 2 million years.
