On Tuesday, August 12th, there was a fairly large ice dam break on a lake along the edge of the ice sheet. Annie and I were out sampling lakes near the margin when we saw the remnants of what appeared to be a much larger lake. The first sign was a group of large blocks of ice sitting on the slope about 20 meters above the height of the current water level. When we started looking around, we noticed the high water line all around the valley and even on the ice. It also appears that there are many past fluctuations in the water height in this lake as well, as there is a lack of vegetation up to a certain height on the slope all around the area (much higher than the recent lake level). When we returned to KISS later that evening, our suspicions were confirmed by a group of students researching the meltwater hydrology. There was a water rise in the river in Kangerlussuaq but nowhere near as extreme as the flooding that destroyed the bridge.
