Backyard and Beyond

Corrugated tidal flats, a rippled landscape.
Some water is still trapped yards from the lowtide front. Somebody’s in there.
These sandy spaghetti-like strands are casings, thrown out of wormholes in the sand.
While we’re on the subject of worms, these are another kind of worm that build tunnels on shells (in this case a big Hardshell Clam.)
