In early winter, Tlingit trappers near Teslin, Yukon, observed something out on the land that stoked serious concern: the snow was unusually deep. Before long, they relayed the message to the Teslin Tlingit Council. "They said we're going to have a problem here with flooding," said Chief Eric Morris. "They couldn't even get to their traplines." Fast forward to June and a flood warning was issued for the community, followed by an evacuation alert for certain parts of it. The water rose so high it surpassed last year's record-breaking flood levels by roughly one metre.
