Movement

The first time I saw this, I assumed that the rangers at Whitesands had been at work with tractors, flattening out the areas between the dunes. A ranger explained that this is what is left behind when the dunes move. Eventually, the ridges will smooth out and the area between dunes will appear flat.

Wind is the agent of change at Whitesands and the dunes are constantly in motion. A couple of ideas interest me in that -- first, I like the idea that there is imperceptible movement going on all the time and that while the immediate effect isn't noticeable, the cumulative effect is. You know the effect -- you haven't seen little cousin Boo in ages and when he walks in there's a sudden discordance between your mental image and this guy standing in front of you. Had you been watching daily, there would have been no need to comment. The second idea I like is that nothing can change without leaving some evidence of change behind.
