Below the ridges and seracs of the Athabasca Glacier icefall can be found several pools of some of the most pristine water on Earth. Trapped temporarily in pockets of glacier ice before reaching a fissure and draining away into the great Athabasca River, the crystal-clear water shines with an incredible blue-green color. But it might as well be blood-red, since it’s the life of the glacier, draining away.
