Ski tracks along the Susitna River
The past week I was in Talkeetna and took a walk along the Sustna River. Some one had been cross-country skiing a few days prior to my walk, and the skier left interesting tracks as he-or-she herring-boned up a small rise. The tracks are not depressions in the snow. Rather, they are ridges. The skier's initial ski thrust compacted the snow, and wind subsequently eroded the snow around the tracks.
