Neo-lithic tombs, plus mounds with top-layer soil that may have pollen of the era intact, have been aerially located in Hampshire, England, 15 miles from Stonehenge.
If any of my English ancestors are involved from way-back-when, perhaps I can figure out why I've always been so allergic to certain flower, tree, and grass pollens, eh?
Ahh-choo and fond congratulations to the hard-working archaelogical community!
