Although this project failed to produce results, it is an interesting example of a technique which could be useful in tracing the Vikings in Vinland.
In 2014 archaeologist Sarah Parcak, using near-infrared satellite images discovered a possible Norse site at Point Rosee, Newfoundland. This created a great deal of interest and publicity, although subsequent investigation discovered no sign of Viking activity.
Subsequent excavation in 2015 and 2016 failed to discover traces of Norse occupation
The report of the excavations said that they “found no evidence whatsoever for either a Norse presence or human activity at Point Rosee prior to the historic period” The report continued: “None of the team members, including the Norse specialists, deemed this area as having any traces of human activity.”
