Beerenberg is a stratovolcano dominating the northeastern end of the Norwegian island of Jan Mayen. It is high and is the world's northernmost subaerial active volcano and the only volcano in Norway. The volcano is topped by a mostly ice-filled crater about wide, with numerous peaks along its rim including the highest summit, Haakon VII Toppen, on its western side. Name Its name is Dutch for "Bear Mountain", and comes from the polar bears seen there by Dutch whalers in the early 17th century.

Jan Mayen
Jan Mayen () is a Norwegian volcanic island in the Arctic Ocean with no permanent population. It is long (southwest-northeast) and in area, partly covered by glaciers (an area of around the Beerenberg volcano). It has two parts: larger northeast Nord-Jan and smaller Sør-Jan, linked by a wide isthmus. It lies northeast of Iceland (495 km 05 miNE of Kolbeinsey), east of central Greenland, and west of the North Cape, Norway. The island is mountainous, the highest summit being the Beerenberg volcano in the north. The isthmus is the location of the two largest lakes of the island, Sørlaguna (South Lagoon) and Nordlaguna (North Lagoon). A third lake is called Ullerenglaguna (Ullereng Lagoon). Jan Mayen was formed by the Jan Mayen hotspot and is defined by geologists as a separate continent. Although administered separately, in the ISO 3166-1 standard, Jan Mayen and Svalbard are collectively designated as ''Svalbard and Jan Mayen'', with the two-letter country code " ...
