Until Columbus arrived in the Americas, El Hierro was seen as the threshold of the known world and, for a time, the Meridian that delimited it. Half a millennium later, the last western island of the Canaries is teeming with exuberant volcanism.
If we went back to the geological ends of time, we would find southwestern Norway filled with huge mountains and a burning magma that successive glaciers would shape. Scientists have found that the mineral that predominates there is more common on the Moon than on Earth. Several of the scenarios we explore in the region's vast Magma Geopark seem to be taken from our great natural satellite.
