Also with these formations I have no idea what they are. These strange rings of smaller "bubbles" at least look old and that is why I have added them to the collection here. What is this? Cattle gates with a yard in the middle? Layouts of smaller huts arranged in a circle around an inner courtyard? Nothing can be said about their age from above either. It could be decades, centuries or, at least I hope, millennia.
So again my question:
If anyone knows what it is, I would be very happy to receive some info.
