Jasper NP: Medicine Lake
Medicine Lake - along the Maligne lake road - is a fascinating natural phenomenon, as this lake exists only "seasonal", when the spring melts the glacier ice which in turn feeds the lake. The water then leaks slowly through a cave system - imagine someonone pulling the stopper in a gigantic bathtub - and reappears in other places, like Maligne Canyon. We where lucky and saw the lake properly filled, though in places the water was just ankle-high - with rubber boots you could wade through to the center of the lake. It is possibly to walk a little along the lake-shore, and it is very likely that you will see Pikas (small alpine rodents) on the way.
