The wall of the Red Chris tailings pond is a little less than 350 feet, or about the height of a 35-story building. It follows the same design as the Mount Polley tailings dam, which broke in 2014, sending 24 million cubic meters of toxic mine tailings into the Fraser River watershed. It is designed, however, to hold 305 million cubic meters of mine waste — seven times more than Mount Polley. Both mines are owned by Imperial Metals. (Courtesy Photo | Garth Lenz via Salmon State)

Could Canadian mine be cautionary tale for Southeast?

Experts weigh in on environmental and economic hazards.
