 We are in a really extraordinary place here. I mean this is almost like a time capsule.

There is very little landscape change extraordinarily¹ from *. So it is a special place.

The unexpected discovery of a rare and actual phenomenon, may also explain the beginning of Stonehenge’s mystical reputation.

Well, something that is really interesting about this site is it appears that it is not all about the practical. We noticed a really strange phenomenon with flint. We’ve got a chemical reaction going on here. The flint is turning brown because there are traces of iron in the spring water. Now that is typical. A lot of places on the edges of fresh water, ponds, lakes, and rivers. But there is something peculiar² happening here. When a stone like this is pulled out of the water, and is kept out of the water for about two to three hours, something extraordinary happens. It turns into a really bright, almost of violent * pink.

The remarkable³ change is triggered by rare algae⁴ in the spring water.
