    Reminds me of banded iron. I find myself wondering, how do you get heavily iron coated sand laminated with a pure white sand? They would have to be in the region to end up layered together, but the water would have to be very localized to stain one set of sand grains without ever touching a nearby set.

Where in the World is this GigaPan?

Sorry, this gigapan has no location information.
