During a nature walk inside an old abandoned quarry I stumbled upon strange spirals that appear to be naturally formed.
What could cause this spiral formation? Is it a known phenomena?
To clarify , the images are from the same place , but made with difference of couple of days. I took the photos during Winter time in Israel.
The Quarry was abandoned decades ago, so i don't think that this is a result of the working equipment.
Also i have been looking at photos of crop circles but it looks like the two are not related.
