Glacial run-off from Fox Glacier shaped these patterns in the soft sand. The subtle blue tones of the milky water made a nice contrast with the brown background. The crucial aspect of this photo is the ambiguity of scale. One could imagine this being an aerial image of a river coursing through a delta – in fact, the entire frame lay at my feet.
