Tracking the long-term limnological impacts of silver mining near Keno City (Yukon, subarctic Canada)

Mining in Northern Canada has been known to cause major environmental repercussions; however, monitoring data are scarce or non-existent. Here, we use a multi-proxy (metals, bioindicators, pigments) paleolimnological approach to track the impacts of mining activity near Keno City, on the traditional land of the First Nation of Na-Cho Nyäk Dun, in central Yukon (Canada). Silver was discovered in the early-1900s, primarily on or between two hills …
