Walking on Limantour Beach in Marin County, California, we had to make our way against major headwinds. Small groups of ankle-high bluffs dotted the long beach. They were clumps of knotted dry seaweed which prevented the sand from being blown smooth and flat, an unexpected illustration of the relationship between vegetation, sand, and erosion, reflecting the high cliffs all around.

There was also this crab shell that formed its own miniature sand bluff.
