Big Ben is a volcanic massif that dominates the geography of Heard Island in the southern Indian Ocean. It is a composite cone with a diameter of approximately 25 kilometres. Its highest peak is Mawson Peak, which is 2,745 m above sea level. Much of it is covered by ice, including 14 major glaciers which descend from Big Ben to the sea. Big Ben is the highest mountain in Australian Territory. A smaller volcanic headland, the Laurens Peninsula, extends approximately 10 km to the northwest, created by a separate volcano, Mount Dixon; its highest point is Anzac Peak, at 715 m.
