Mount Terror is a large shield volcano that forms the eastern part of Ross Island, Antarctica. It has numerous cinder cones and domes on the flanks of the shield and is mostly under snow and ice. It is the second largest of the four volcanoes which make up Ross Island and is somewhat overshadowed by its neighbor, Mount Erebus, 30 km (19 mi) to the west.[3] Mt. Terror was named in 1841 by Sir James Clark Ross for his second ship, HMS Terror.[1] The captain of Terror was Captain Francis Crozier who was a close friend of Ross.

The rocks at the summit have not been studied, but lower areas have been studied and rocks from those areas range from 0.82 to 1.75 million years old. Mount Terror shows no signs of volcanic activity more recent than that.

The first ascent of Mt. Terror was made by a New Zealand party in 1959.

Terror Point (77°41′S 168°13′E / 77.683°S 168.217°E / -77.683; 168.217), located just below Mt. Terror, is the eastern limit of Fog Bay, 6 km (3.7 mi) WNW of Cape MacKay on Ross Island. The name was first used by members of the British National Antarctic Expedition, 1901–04, and was apparently applied in association with Mt. Terror which overlooks this point from the northeast.[4]

Terror Saddle (77°31′S 168°5′E / 77.517°S 168.083°E / -77.517; 168.083) is one of three prominent snow saddles on Ross Island, located c.1600 m between Mount Terra Nova and Mount Terror. Named in association with Mount Terror, which rises to 3262 m to the east of this saddle.

Terror Glacier (77°37′S 168°3′E / 77.617°S 168.050°E / -77.617; 168.050) is a large glacier between Mount Terra Nova and Mount Terror on Ross Island, flowing south into Windless Bight. So named by A.J. Heine of the New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1962–63, because of its association with Mount Terror.
