Mount Waesche is the southernmost of a N-S chain of volcanoes in central Marie Byrd Land, 20 km SW of Pliocene Mount Sidley. The Waesche shield was constructed around 1.0 Ma on the SE rim of the 10-km-wide Chang Peak caldera; pre-caldera Chang Peak lavas were erupted about 1.6 Ma. Satellitic cinder cones, some aligned along radial fissures, are located on the SW flank. The youngest dated products suggest a pulse of effusive activity between about 200,000 and 100,000 years ago.
