An unexcavated archaeological site, potentially from the Viking Age, was washed away by a glacial lake outburst flood in South Iceland earlier this autumn. Iceland Magazine reports:

Uggi Ævarsson, the Cultural Heritage Manager of South Iceland[,] tells RÚV that the ruins had neither been charted nor catalogued, let alone explored by archaeologists.

This is all the more serious because the ruins could have dated back to the Viking Age, he tells RÚV: “This is a great loss. Now we are missing another piece of the puzzle which is the settlement history of Skaftártunga region. These floods come regularly here, and then the nearby volcano Hekla also has her regular eruptions, all of which makes the settlement history of this region extremely interesting.”

Glacial lake outburst floods are highly destructive. Outside of priceless loss to the historic record that the loss of such a site may cause, this particular flood caused significant damage to the region, washing away a road and causing damage to several farms in the region, resulting in losses of "ISK Hundreds of Millions" as reported by Iceland Review Online.
