Ruins recently discovered on Greenland may be the Vikings’ most northerly year-round hunting outpost on the icy island.

According to Knut Espen Solberg, leader of ‘The Melting Arctic’ project mapping changes in the north, the remains uncovered in past weeks in west Greenland may also be new evidence that the climate was less chilly about 1,000 years ago than it is today.

“We found something that most likely was a dock, made of rocks, for big ships up to 20-30 metres (60-90 ft) long,” he said.
