Medicine Lake (crs)
|Start Slide Show|
Medicine Lake is a geologic anomaly in the sense that it is not actually a lake but rather an area in which the Maligne River (flowing from Maligne Lake into the Athabasca River) backs up and suddenly disappears underground. During the summer months during intensified meltwater runoff the lake (which during the winter months is a meandering frozen river) fills to levels which fluctuate over time and with the runoff events. It becomes laden with water (lake) until it can slowly drain as the runoff) is reduced. The underground system is extensive and during the 1970s researchers used a biodegradable dye to determine the underground river's extent. The dye showed up in many of the lakes and rivers in the area to the point where it became clear that the underground system was one of the most extensive in the world.
