Melt-Lake on Humboldt Glacier

A melt-lake lying on the surface of Humboldt glacier just inboard of the calving front. Bergs and other calved debris can be seen In the far distance, floating in the fjord of Kane Basin. As melt-lakes like this get larger in the warmer atmospheric temperatures of summer, the accumulated mass of water exploits weaknesses in the glacier's surface and flows outwards towards the sea via ravines, crevasses and moulins. Humboldt is the widest glacier in the northern hemisphere, it has a front of 110 kilometers across.
