Toney Mountain is a 3595 m high probably extinct shield volcano in Marie-Byrd-Land in western Antarctica . The elongated mountain range is around 60 km long and rises around 58 km southwest of the Kohler Range .
The highest point of the volcano is called Richmond Peak . The age of a rock sample from the mountain top showed an age of about 500,000 years. Toney Mountain could have been volcanically active into the Holocene ; it is believed to be a possible source of ash layers deposited in the ice near Byrd Station over the past 30,000 years .
The first sightings of the mountain go back to 1940 during flights during the United States Antarctic Service Expedition (1939-1941) under the direction of the American polar explorer Richard Evelyn Byrd . It was mapped in December 1957 by an expedition from Byrd Station to the Sentinel Range . Its head, the American geophysicist and polar explorer Charles Bentley , named the mountain after George Robert Toney (1918–2008), who headed the Byrd station in 1957.
