Trail Glacier (73°34′S 61°35′E) is a broken mountain glacier on the southern side of Mount Menzies, about 2 nautical miles (3.7 km) from the summit. It is about 5 nautical miles (9 km) long and 3 nautical miles (6 km) wide. The glacier flows from a snowfield at about 2,750 m down a steep slope for at least 900 m vertically, then spreads out and merges with the ice sheet a few mi from the south side of the mountain. Mapped from ANARE (Australian National Antarctic Research Expeditions) air photos and surveys of the Prince Charles Mountains, 1960-61. Named by Antarctic Names Committee of Australia (ANCA) for D.S. Trail, geologist who led an ANARE field party to this feature in December 1961.
