127 viewsDuring the first year of the Antarctic Megadunes expedition, researchers found "pipes" in the hard-packed snow. The pipes start just beneath the surface and go down into the snow. One deep pipe, like the one shown here, was at least 6 feet (1.9 meters) deep. The pipes appear to be cracks that form near the surface of the ice and then freeze over.
