NOAA's Arctic division maintains a couple of webcams at the North Pole, and one of them is showing a pretty impressive meltwater lake forming around it. Previous years show small ponds forming and refreezing throughout the summer, but this year nearly all the snow in view of the camera has melted into a lake-sized slush.

Check out this time lapse video of the lake forming. Much more photos and videos from this year and previous years at NOAA's website.
