Background
Mount Waesche is the southernmost of a N-S-trending chain of volcanoes in central Marie Byrd Land. Mount Waesche is located 20 km SW of Pliocene Mount Sidley, Antarctica's highest volcano, and was constructed on the SE rim of the 10-km-wide Chang Peak caldera. Pre-caldera Chang Peak lavas were erupted about 1.6 million years ago (Ma) and the Waesche shield formed about 1.0 Ma. Waesche may have been active during the Holocene and is a possible source of ash layers in the Byrd Station ice core that were deposited during the past 30,000 years. The youngest lavas are too young to date by Potassium-Argon. Satellitic cinder cones, some aligned along radial fissures, are located on the SW flank.---
