Crystal Sound (66°23′S 66°30′W / 66.383°S 66.5°W) is a sound between the southern part of the Biscoe Islands and the coast of Graham Land; northern limit Cape Evensen to Cape Leblond, southern limit Holdfast Point, Roux Island, Liard Island and Sillard Islands. So named by United Kingdom Antarctic Place-Names Committee (UK-APC) in 1960 because many features in the sound are named for men who have undertaken research on the structure of ice crystals.
