“Right on. It would be easy to believe these were man made, unless someone can come with a geological process that I’m not aware of.”
These features are linear sand dunes, and they cannot be manmade due to their formation by bidirectional winds tens of thousands of years ago as evidenced by the geological corings of those features. The corings of the dunes reveal their formation by the winds drowning the prior geological strata and biological material in sand piled up into linear dune formations.
Sounds plausible. Can you tell me what “bi-directional winds” are? Are there other examples of equally spaced “linear dunes” covering such large areas?
