Moles are being used by the Viborg Museum in Denmark to help assess archaeological sites by digging up small artifacts that indicate the potential presence of a structure underneath.

A different breed of archaeologist is being mobilized in Denmark to help uncover the past. 

Officials at the Viborg Museum have deployed moles--with approval from the local cultural authority--to explore a historical site south of Viborg where it is believed that remnants from a Middle Ages fort have been buried. 

In what one of the archaeologists has termed “moleology,” using the burrowing animals has become an effective way of recovering artifacts and other small items from the ground that indicate where larger structures may be.
