Thurston Island
Cox Glacier () is a small glacier immediately east of Rochray Glacier on Thurston Island, flowing south to Abbot Ice Shelf in Peacock Sound. It was delineated from air photos taken by U.S. Navy Squadron VX-6 in January 1960, and named by the Advisory Committee on Antarctic Names for Lieutenant Jerry G. Cox, a helicopter pilot aboard , who made exploratory flights to Thurston Island in February 1960. Jordan Nunatak stands between Cox and Rochray Glacier.
