Background

Toney Mountain in east-central Marie Byrd Land is a linear, E-W-trending volcanic massif with a 3-km-wide summit caldera and several satellitic cinder cones. A sample from the top of the felsic shield volcano gave a Potassium-Argon date of 0.5 million years ago. Some of the ash bands in the Byrd Station ice core deposited within the past 30,000 years may have been from Toney Mountain, and Holocene activity is possible (LeMasurier and Thomson 1990). Several small cinder cones occur along the crest of the 14-km-long massif, which is almost entirely mantled by glaciers.
