[Rockhounds] Stealing a river

[Kreigh Tomaszewski]

In the blink of a geological eye, climate change has helped reverse the
flow of water melting from a glacier in Canada’s Yukon, a hijacking that
scientists call “river piracy.”

This engaging term refers to one river capturing and diverting the flow of
another. It occurred last spring at the Kaskawulsh Glacier, one of Canada’s
largest, with a suddenness that startled scientists.

A process that would ordinarily take thousands of years — or more —
happened in just a few months in 2016.

I saw this river just a few month's before it disappeared.
