Iceland’s Ice cave Katla This cave is constantly changing due to melting and freezing of ice and can look different day to day. It was formed by water flowing from the glacier through small cracks in the ice. The cave has black layers from volcanic ash and create black streaks frozen in the cave. #glaciers#iceland#ice#blue#cold#icecaves#icecavesicelandtour#katla#icelandtravel katlatrack icelandair iceland iceland.explore localguide inspiredbyiceland
