Slims River

The Slims River (Ä’äy Chù) was a glacially fed river in the Canadian territory of Yukon. Until 2016, it originated in the Kaskawulsh Glacier, then ran approximately 15 mi (24 km) into the southern terminus of Kluane Lake.

Over the course of a few days in the spring of 2016 the flow of the river was changed. Where the meltwater of the Kaskawulsh Glacier had been draining in two directions, now it was all draining into the south-flowing Kaskawulsh River, and further on into the Gulf of Alaska, drastically reducing the size of the Slims. Researchers suggested the change in flow could be due to manmade climate change; this was the first time manmade climate change was implicated in the reorganization of a river.
