minidunes

Rather than being an aerial view of some hot expanse of equatorial desert, this is a small scale cold wet winter seashore scene. When winter storm surf pounds on the sand and increases the slope of the beach, the uppermost beach can be quite flat. Often the level of such flat areas is below the highest edge of the pushed up lower beach. When water pools there at high tide most waves can't make it over the barrier with much force. The gentle washing of these waves back and forth across the shallow pool can create whole fields of small sand dunes. When the tide goes out and the water drains down through the sand, this is what's left behind. The same phenomenon occurs commonly in very flat shallow beaches just below the wave line. The difference here is that when the tide goes out, everything is exposed to beachcombers and wandering photographers.

Vertical scale is about 5 cm max height.

The original jpg file was cropped slightly, but otherwise unadjusted.
