Website here, film itself not online
That's interesting in itself. The sat data is v. cool and seems able to find even very faint evidence, but it has not turned up promising sites on every cove and headland on the eastern seaboard, to say the least.
In the end the film's conclusion was... inconclusive. Actual trenching on the site at Point Rosee revealed likely signs of turf buildings right where the telemetry pointed -- the technology worked -- but the iron was not iron, and the organics all carbon-dated to much later. A well informed sceptic could probably argue it's as likely to be an eighteenth-century outpost of the fishery as a Norse encampment.The film's evidence turned out a lot more sketchy -- and its claims more hedged -- than recent press reports indicated. Much work remains to be done.
