- A Canadian Icecap emailer noted during the cold war there were two massive radar sites built on the Greenland icecap now abandoned. They are called Dye-2 and Dye-3. When built they sat high above the snow, recent pictures (go to icecap.us to see these pictures) show how the snow is building up around them, proving the snow build-up in recent times. The site is slowly disappearing into the snow. Its outbuildings are no longer visible and drifting snow will consume it completely one day, but that day appears to be decades away.
