Dry weather reveals archaeological 'cropmarks' in fields (BBC)

[eppur_se_muova]

Hundreds of ancient sites have been discovered by aerial surveys, thanks to a dry start to the summer, English Heritage has said.

The surveys show marks made when crops growing over buried features develop at a different rate from those nearby.

The newly-discovered Roman and prehistoric settlements include a site near Bradford Abbas, Dorset.

The Roman camp was revealed in June after three sides became visible in sun-parched fields of barley.

The lightly-built defensive enclosure would have provided basic protection for Roman soldiers while on manoeuvres in the first century AD and is one of only four discovered in the south west of England, English Heritage said.

Is anyone looking in this country? Maybe we could find another Cahokia.

1. We do have people who do similar research here.

But you'd need very similar weather conditions to get similar results. Plowing has almost erased such crop marks here. You can really see the difference when looking at the earliest aerial photographs of some sites in Ohio, and comparing them to modern imagery.

Here's some cool stuff being done with LIDAR, though:
