There is a mountain in Antarctica known as Mount Chapman. It is a mountain with three peaks, 2,715 meters high (8,907 feet), very steep sides, and a large rock cliff on its northern side. It can be found at the westernmost end of the Whitmore Mountains. It was named after William H. Chapman of the United States Geological Survey (USGS), a cartographer who participated in the Horlick Mountains Traverse (1958–59) and made a survey of the Whitmore Mountains on January 2, 1959. This honor was bestowed upon him by the Advisory Committee on Antarctic Names. During his time in the Antarctic, Chapman conducted a number of successful surveys, including one in the Pensacola Mountains (1957–58).
