The Humboldt glacier which calves bergs into the Kane Basin, the widest glacier in the northern hemisphere, it has a front of 110 kilometers across. Meltwater waterfalls cascade over the front of Humboldt glacier, cutting channels into the calving face. Meltwater caused by atmospheric warming of the glacier's surface runs over the ice towards the sea via a network of ravines, eventually flowing into the fjord of Kane Basin. July 2009
