Panorama of Medicine Lake, Jasper NP
Medicine Lake known locally as the "disappearing lake" . The Maligne River fees the lake and in summer, waters from nearby melting glaciers fill the lake. In fall and winter, when the snowmelt stops, the lake begins to disappear, draining out through sinkholes at the lake bottom. The water flows through an underground cave system, before surfacing 10 miles downstream in Maligne Canyon.
