I do not know what critter creates these ridges and riddles in the sand, but every morning I find them at the edge of the dune grass where sand is mostly dry. Whatever the source, I find the images fascinating and fun.
The very low tide had hollowed-out swales, leaving lovely feather patterns.

Neat patterns! 🙂
Kind of like an erase-a-sketch, there are new drawings in the sand every day!
Fascinating patterns 🙂
I’m so glad Minustide has identified the probable source!
That was lucky to have a reader with a probable ID 🙂

Great post! I wonder if those trails are made by Alloniscus. I wrote some words and pics about this little crustacean a while back. Trails too. What do you think? https://theoutershores.com/2015/11/11/alloniscus-of-the-backshore/
Thank you! I was hoping you’d see my post and be able to enlighten me!! I’m sure you’re right — the tracks and traces are much the same, and as I was taking one of the shots I saw what I thought was a sowbug scooting along nearby — why would I take a snap of a sowbug?! Next time!!
The intricacy and organic nature of the patterns is fascinating!
My feelings as well! Thanks for visiting and commenting.
