Mine Field : The trout- and salmon-rich rivers of southeast Alaska face a new danger that few Americans have heard about.

There’s the Galore Creek, Red Chris and Schaft Creek open-pit mines, planned for tributaries of the Stikine River; the Tulsequah Chief underground mine, on a tributary of the Taku River (in most years southeast Alaska’s biggest salmon producer); and the Kerr-Sulphurets-Mitchell (KSM) combined open-pit and underground mine, on the headwaters of the Unuk River. This last one would be roughly the size of Pebble. It would leach out gold with cyanide, destroy three mountains, fill a valley with 1.62 billion tons of toxic tailings held between two Hoover-size dams and generate 118,000 gallons of wastewater a minute. The mine site and the tailings area would be connected by twin 14-mile tunnels, with at least six of the miles beneath glaciers.
