Hays Mountains () is a large group of mountains of the Queen Maud Mountains, surmounting the divide between the lower portions of Amundsen and Scott Glaciers and extending from the vicinity of Mount Thorne on the northwest to Mount Dietz on the southeast. Discovered by R. Admiral Byrd on the South Pole flight of November 28-29, 1929, and mapped in part by the Byrd Antarctic Expedition geological parties to this area in 1929 and 1934. Named by Byrd for Will H. Hays, former head of Motion Picture Producers and Distributors of America.
Mount Astor, a prominent peak in the range, was named by R. Admiral Byrd for Vincent Astor, of the Astor family, for his philanthropic contributions to the 1929 expedition.[1]
