This is a short recording made while walking over a frozen section of Stora Värtan on the way back from the island of Bastuholmen to the mainland at Näsbypark in the Stockholm archipelago. From the small park where we stopped to the island was about half a kilometer over the frozen sea. The surface was made up of patches of exposed ice with shallow drifts of snow. Stopping momentarily it was possible to hear the low booming sound of the ice moving. Stora Värtan translates as ‘Big Darkness’.
