Mount Madison (Antarctica)
Mount Madison is a prominent, largely ice-covered mountain in Antarctica, rising to west of Cape Selborne, on the south side of Byrd Glacier. It was named by the Advisory Committee on Antarctic Names for Lieutenant Commander Douglas W. Madison, aide to the Commander, U.S. Naval Support Force Antarctica, 1961–62, and Public Information Officer, 1963–64.
Madison Terrace is a rectangular terrace, 6 nautical miles long and 3 nautical miles wide, abutting the south part of Mount Madison on Shackleton Coast. Ice draining from Mount Madison covers the terrace, which terminates in a line of icefalls within Couzens Bay. Named by US-ACAN in association with Mount Madison.
