About Toney Mountain
Toney Mountain is a shield rising to 3,595 meters (11,795 feet) in Antarctica's Antarctic-Scotia Volcanic Regions. No historical eruptions have been recorded, though the volcano is classified based on geological evidence of past activity.
Geography & Climate
Toney Mountain is located in Antarctica, within the Western Antarctica Volcanic Province of the broader Antarctic-Scotia Volcanic Regions. Situated at 75.80° S, 115.83° W in the Southern Hemisphere, the volcano lies within a polar climate zone. Standing at 3,595 meters above sea level, Toney Mountain towers above the alpine zone, where vegetation gives way to bare rock, snow, and ice for much of the year. The high elevation means the upper slopes experience significantly colder temperatures than surrounding lowlands. The volcanic landform is characterized as a shield, which describes the physical shape and structure of the volcanic edifice as observed from the surface.
GVP Reference Summary
Toney Mountain in east-central Marie Byrd Land is a 50-km-long volcanic massif with a 3-km-wide summit caldera and several satellitic cinder cones. Several small cinder cones occur along the crest of the massif, which is almost entirely covered by glaciers. A felsic sample from the summit area gave a Potassium-Argon date of 500,000 years.
