Mount Takahe is a 3460 m snow-covered shield volcano in Marie Byrd Land, Antarctica, 200 km from the Amundsen Sea. It is about 30 km wide with parasitic vents and a caldera up to 8 km wide. Most of the volcano was formed by trachytic lava flows. It reached its present height about 200,000 years ago. Snow, ice, and glaciers cover most of Mount Takahe. With a volume of 780 km3, it is a massive volcano; the parts of the edifice that are buried underneath the West Antarctic Ice Sheet are probably even larger. It is part of the West Antarctic Rift System along with eighteen other known volcanoes. A major eruption took place around 17,700 years ago, possibly forming an ozone hole over Antarctica. The last eruption occurred about 7,600 years ago; there is no present-day activity. The name of the volcano refers to the takahē, a flightless bird from New Zealand.
