91 viewsAn even closer close-up of the wall of the snow pit, showing a couple of layers in the snow. These particular kinds of layers form when big snow storms occur with strong winds that cause the snow to compact at what was then the surface. Other layers may be caused by melting and refreezing of snow. Photo by John Maurer, CIRES/NSIDC, University of Colorado.

105 viewsWhile Nic and Russ are off working on the weather station at NASA-SE, I'm digging another snow pit. This one is 2.5 meters (8 feet) deep! At that point, I reached the layer from the previous year's snow surface.
