In Northumberland, moles assist in archaeology

In Northumberland, England, volunteers are sifting through mole hills looking for artifacts from Epiacum, a Roman fort 12 miles south of Hadrian's wall.

Because of the site's official status as an ancient monument, archaeological excavation is banned. The moles do not seem to care about that and have dug up artifacts while digging their burrows. Many tell-tale Roman artifacts have been found in the mole hills including pottery, nails, and a bead.
