About ten miles off the coastline of Reykjanes Geopark is Eldey. The name means Fire Island. This 246 feet tall basalt rock is home to a colony of 16,000 pairs of gannets. This mostly white seabird has an enormous wingspan up to six feet tipped in black. It is remarkable to watch them retract their wings and plummet into the water at speeds up to 60 miles per hour.
