Geology

Mount Terror is a 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 that make up Ross Island.

Geography

The rocks at the summit have not been studied, but rocks from the lower areas range from 0.82 to 1.75 million years old, and Mount Terror shows no signs of more recent volcanic activity. The first ascent of Mount Terror was made by a New Zealand party in 1959.Template:Fact The mountain is to the west of Cape Crozier, and east of Mount Terra Nova and Mount Erebus.Template:Sfn

Kienle Nunataks

Template:Coord. Three aligned nunataks to the north of Mount Terror in northeast Ross Island. The nunataks trend east-west for Template:Convert and rise to about Template:Convert. The central nunatak is Template:Convert north-northeast of the Mount Terror summit. At the suggestion of P.R. Kyle, named by Advisory Committee on Antarctic Names (US-ACAN) after Juergen Kienle (d.), Geophysical Institute, University of Alaska, Fairbanks, a United States Antarctic Project (USAP) team leader for the investigation of volcanic activity and seismicity on Mount Erebus in six field seasons, 1980-81 through 1985-86.Template:Sfn

Mount Sutherland

Named by Advisory Committee on Antarctic Names (US-ACAN) (2000) after Alexander L. Sutherland, Jr., Ocean Projects Manager, OPP, NSF, with responsibility for directing operations and logistics for United States Antarctic Project (USAP) research vessels from 1989; responsible for acquisition of the Research Vessel/Ice Breakers Nathaniel B. Palmer and Laurence M. Gould.Template:Sfn

Rohnke Crests

Template:Coord. Two rock ridges, about Template:Convert high, that are parallel and rise above the general ice mantle on the southeast slopes of Mount Terror. This feature is east of the head of Eastwind Glacier and Template:Convert northeast of Conical Hill. Names in association with Eastwind Glacier after Captain (later Rear Admiral) Oscar C. Rohnke, USCG, who commanded United States Coast Guard Cutter (USCGC) Eastwind in Ross Sea during United States Navy (United States Navy) Operation Deep Freeze (OpDFrz) I, 1955-56.Template:Sfn

Moore Peak

Template:Coord. A peak rising to Template:Convert high on the west slope of Mount Terror, Ross Island. The peak is Template:Convert west-southwest of the summit of Mount Terror and Template:Convert south of Mount Sutherland. At the suggestion of P.R. Kyle, named by Advisory Committee on Antarctic Names (US-ACAN) (2000) after James A. Moore, a member of the New Mexico Institute of Mining and Technology team on Mount Erebus in the 1983–84 and 1985-86 field seasons. He completed his M.S. thesis on the geology of Mount Erebus.Template:Sfn

Ohau Peak

Template:Coord. A sharp rock peak Template:Convert northeast of the summit of Mount Terror on Ross Island. The feature rises to about Template:Convert high and is central in three aligned summits Template:Convert north of Mount McIntosh. Named by New Zealand Geographic Board (NZGB) (2000) after a peak near the locality of Tekapo (see Tekapo Ridge), New Zealand.Template:Sfn

Giggenbach Ridge

Template:Coord. A north-south chain of summits, Template:Convert long, located to the west and northwest of Mount Terror. The ridge rises to about Template:Convert west of Mount Terror, but descends to Template:Convert at the north end. Named at the suggestion of P.R. Kyle, named by Advisory Committee on Antarctic Names (US-ACAN) (2000) after Werner F. Giggenbach, Chemistry Division, DSIR, who worked in the NZAP at Mount Erebus in four field seasons during the 1970s. He rappelled into the Inner Crater of Mount Erebus in 1978, but had to be pulled out when an eruption showered him and colleagues on the crater rim with volcanic bombs. He was one of the leading volcanic gas geochemists of the period.Template:Sfn

Chuan Peak

Template:Coord. A peak, about Template:Convert high, located Template:Convert northeast of Barker Peak in the south part of Giggenbach Ridge, Ross Island. At the suggestion of P.R. Kyle, named by Advisory Committee on Antarctic Names (US-ACAN) (2000) after Raymond L. Chuan who, as a scientist with the Brunswick Corporation, Costa Mesa, CA, undertook many airborne surveys of volcanic aerosols from Mount Erebus and also did sampling at the crater rim, 1983–84 and 1986–87; investigator (with Julie Palais) on a project which examined aerosols between Mount Erebus and the South Pole.Template:Sfn

Manahan Peak

Template:Coord. A prominent peak Template:Convert east of Giggenbach Ridge in northeast Ross Island. The peak rises to over Template:Convert high Template:Convert northwest of the summit of Mount Terror. Named by the Advisory Committee on Antarctic Names (US-ACAN) (2000) after biologist Donal T. Manahan, who worked eight seasons in Antarctica from 1983; United States Antarctic Project (USAP) principal investigator in study of early stages (embryos larvae) of marine animals; chair, Polar Research Board, National Academy of Sciences, 2000.Template:Sfn

Barker Peak

Template:Coord. A peak Template:Convert west-northwest of Mount Terror on Ross Island. The feature rises to about Template:Convert high and is the western of two peaks near the south end of Giggenbach Ridge. Name by New Zealand Geographic Board (NZGB) (2000) after Major James R. M. Barker, officer in command at Scott Base, 1970–71; a NZAP manager, 1970-86.Template:Sfn

Joyce Peak

Template:Coord. A peak rising to over Template:Convert high in the north-central part of Ross Island. It stands west of the main summits of Giggenbach Ridge and Template:Convert south-southeast of Wyandot Point. Named by Advisory Committee on Antarctic Names (US-ACAN) (2000) after Karen Joyce, a long-term ASA employee, who from 1990 made 10 deployments to McMurdo Station, including a winter-over; assisted with computers in the Crary Science and Engineering Center.Template:Sfn

Kristin Peak

Template:Coord. A peak rising to over Template:Convert high at the north end of Giggenbach Ridge on Ross Island. The feature is Template:Convert south of Cape Tennyson. Named by Advisory Committee on Antarctic Names (US-ACAN) (2000) after Kristin Larson, who has participated in support activities to United States Antarctic Project (USAP) from 1988, including two winters at McMurdo Station; supervisor, Eklund Biological Center and Thiel Labs, 1988 and 1992; supervisor, Crary Science and Engineering Center, 1992–95; editor, The Antarctican Society newsletter from 1996; later of staff of OPP, NSF.Template:Sfn

Eastern features

Features to the east, towards the Kyle Hills, include:

Tent Peak

Template:Coord. A tent-shaped peak rising to about Template:Convert high midway between Mount Terror and Cape Crozier. It was descriptively named by a party of the New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1958–59, which occupied the peak as an astronomical control station, January 5, 1959, and erected a tent below the peak.Template:Sfn

The Tooth

Template:Coord. A distinctive rock outcrop on the eastern slopes of Mount Terror at an elevation of about Template:Convert. The feature lies Template:Convert south-southeast of Tent Peak and is reported to resemble a fossilized shark's tooth. Descriptively named by a party of the NZGSAE, 1958–59, working in eastern Ross Island.Template:Sfn

Slattery Peak

Template:Coord. A somewhat isolated rock peak, about Template:Convert high, that rises above the ice mantle southeast of Mount Terror. The peak position is additionally defined as Template:Convert southwest of The Knoll and Template:Convert east-northeast of Rohnke Crests. Named after Leo Slattery, who wintered at Scott Base three times, twice as Officer in Charge; Post Clerk on Ross Island, summer 1973-74; Postmaster on Ross Island, summers 1979-80, 1981–82, and 1983–84.Template:Sfn

Pönui Nunatak
