Andrus has a 4.5 km-wide caldera at its summit. The westward face of the mountain 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.
