These two topographic maps cover the island of Jan Mayen. The island’s most prominent feature is Beerenberg, Norway’s only active volcano. Located in the North Atlantic Ocean, 700 km (440 miles) northeast of Iceland, the island is in polar night from November through January. It is heavily glaciated, and occasionally visited by polar bears which cross the ocean ice from Greenland. It has no permanent human population.
The maps were published by the Norwegian ‘Norsk Polarinstitutt’, in 1959. The contour interval is 20 metres, except in areas where persistent cloud cover made aerial survey impossible. As is traditional for maps of Norway’s polar possessions, placenames are written in Nynorsk, and not the more commonly encountered Bokmål.
