Mount Andrus

Mount Andrus is a shield volcano 3.2 km (2 mi) SE of Mount Boennighausen in the SE extremity of Ames Range, in Marie Byrd Land, Antarctica. Mapped by USGS from surveys and U.S. Navy air photos, 1964–68. Named by US-ACAN for Lt. Carl H. Andrus, US Navy, medical officer and Officer-in-Charge of Byrd Station in 1964.

Andrus has a 4.5 km-wide caldera at its summit. Weak fumarolic activity was detected in 1977 at Mt. Kauffman in the northern end of the Ames Range of which Mt. Andrus is the southernmost volcano.

The westward face of Mt. Andrus is drained by the Coleman Glacier, with significant crevassing present.

In an interesting side note, Mt. Andrus was reportedly climbed by one Michael J. Andrus (no relation to Carl H. Andrus) in August 2006 for the purpose of downhill skiing, which would make him the first Andrus to visit the mountain (though perhaps not the last). Carl H. Andrus is himself an avid mountain climber, having summited all 46 of the Adirondack high peaks and having, in his youth, climbed the Matterhorn.
