The iron ore shown to the right was excavated from Skógar, a Viking-age iron-making site in Iceland. The larger piece is about 2cm (less than 1in) in the long dimension. Sometime about 1000 years ago, someone gathered this iron ore, processed it, transported it to the iron smelting site, but for unknown reasons, never used it in a smelt.
