UK heat wave reveals archaeological secrets

The United Kingdom's scorching summer heat wave has revealed hidden archaeological secrets of buried history, with ancient farms, burial mounds and neolithic monuments among fascinating finds.

Lost sites have been turning up all over Britain and Ireland, in areas where grass and crops grow at different heights, or show in different colors, over buried foundations and ditches.
