The Vikings Uncovered

As if to prove that we are living in a fantastical future replete with spectacular job titles, space archaeologist Dr Sarah Parcak employs satellite images of Earth to develop accurate imagery of otherwise long-lost historic settlements. Using this technology, Parcak joins historian Dan Snow and a team of experts who go to extraordinary lengths to prove (or disprove) claims first made in Viking sagas that their settlers explored locations as far-flung as North America some 1,200 years ago – centuries before Christopher Columbus.
