Nature
Kaskawulsh Glacier is a large temperate valley glacier in Yukon’s Saint Elias Mountains within Kluane National Park, formed where its Central and North Arms meet high in the range. At the head of two river valleys, it long fed both the Slims and Kaskawulsh river systems, connecting this region to the Yukon River and Alsek River watersheds. In 2016, the glacier’s retreat abruptly redirected most meltwater away from the Slims River and Kluane Lake into the Kaskawulsh River toward the Alsek and Gulf of Alaska, lowering lake levels. It remains both a major backcountry destination and an important sign of rapid environmental change.
