Bailey Ice Stream is an ice stream on the northern margin of the Theron Mountains, flowing west-southwest to the Filchner Ice Shelf. It was named by the UK Antarctic Place-Names Committee after Jeremy Thomas Bailey (1941 - 65), a British Antarctic Survey glaciologist, who with two companions died in a crevasse accident during a radio echo sounding traverse inland from Halley Station on 12 October 1965. On an earlier traverse in April 1965, Bailey sounded the upper portion of this feature.[1]
