A collapsed lake on the Black Rapids Glacier, seen in June. Ice-dammed lakes like this form throughout spring and summer, particularly on the glacier's northern margin. As the subglacial hydrological system activates, these lakes drain rapidly, often within 24 hours. The resulting subglacial water pressure causes the glacier to lift and accelerate during the drainage. For scale, the ice cliff on the left is roughly 80 feet tall.
