On a sunny day, Medicine Lake looks like an alpine lake. In summer, Medicine Lake is blue-green .
When the warm weather subsides, a curious thing happens: the lake disappears.
Medicine Lake becomes "The Vanishing Lake" as the indigenous people call it.

Jasper National Park is located on the territory of many indigenous peoples, they were the ones who gave Medicine Lake its name. Not only was it curious for them to see a lake drain year after year, there is no obvious drainage system that makes the lake magical. It seems to be the work of the "big medicine" that makes the water disappear every year.

An underground drain runs 17 kilometres downstream and reappears below Maligne Canyon. It is the longest underground drainage system in Canada.
