Figure 8. Racetrack Playa phenomena. Parts show: (a) thin windowpane ice over-riding a recently moved rock (January 9, 2014), (b) water creeping onto the low gradient northern shore of the pond during the December 20, 2013 rock movement (~11:15 am), (c) ice windrows on the eastern shore of Racetrack Playa near the weather station (~1 pm, December 20, 2013); ice panels are ~2–3 mm thick and mixed with mud and rocks scoured from the pond bottom, (d) rock carving a wake through ice that is moving left to right; open rippled water in the foreground (January 9, 2014). Images have been cropped but not otherwise edited. doi:10.1371/journal.pone.0105948.g008
If this theory holds, then it could be scaled up to show how the monoliths used in the erection of Stonehenge were transported by ice and wind from their origins.
