Etched into crops, the outlines of Bronze Age burial mounds surround a roughly 190-foot (57-meter) circular Stone Age temple site about 15 miles (24 kilometers) from Stonehenge in southern England in an undated aerial photo.

Here's an Iron Age fort from Ireland I snapped a picture of in 2007:

6000 yo but erected with such precision. Remarkable. It makes you wonder what the timber architectural forms which have not survived were like. I’m guessing they were far more than the mud and wattle huts that have left evidence elsewhere.

is this back when those Godawful white people were painting themselves blur and orange and eating each other?

while the rest of the non white world was so advanced and all?

leaving behind culture in the jungle no one can find now

the "crop circles" are the results of buried archaeological structures interfering with plant growth.

The plants are acting as bio-indicators which gets me thinking. It might be possible to genetically engineer a plant to change a certain color if its roots find gold. Poison oak might be a good plant to start with since you don't want people touching your new gold.
