The McMurdo Volcanic Group is a large group of Cenozoic volcanic rocks in the western Ross Sea and central Transantarctic Mountains areas of Antarctica. [1] It is one of the largest provinces of alkaline volcanism in the world, having formed as a result of continental rifting along the West Antarctic Rift System .
The giant volcano sponge (Anoxycalyx joubini) is a species of Antarctic sponge. [1] It is one of the largest sponges in the world which can grow up to a diameter of 1.5 metres (5 feet) and 1.95 metres (6.5 feet) in height. [2] The species may have an extremely long lifespan, with estimates of up to 15,000 years. [3]

Ross Island is an island in Antarctica lying on the east side of McMurdo Sound and extending 43 nautical miles (80 km; 49 mi) from Cape Bird in the north to Cape Armitage in the south, and a similar distance from Cape Royds in the west to Cape Crozier in the east. The island is entirely volcanic.
For now, the spaces in the sponge aren't full enough of magma to support an eruption. For that to happen, the system would need more magma to fill more spaces in the crust's "sponge."
Mount Morning is a shield volcano at the foot of the Transantarctic Mountains in Victoria Land, Antarctica.It lies 100 kilometres (62 mi) from Ross Island.Mount Morning rises to an elevation of 2,723 metres (8,934 ft) and is almost entirely mantled with snow and ice.
Observation Hill is a steep 754-foot (230 m) hill adjacent to McMurdo Station in Antarctica and commonly called "Ob Hill". It is frequently climbed to get good viewing points across the continent. Regular clear skies give excellent visibility. Observation Hill is a lava dome and one of many volcanoes comprising the Hut Point Peninsula. [1]
