Laclavère Plateau
plateau in Antarctica
Laclavère Plateau (63°27′S 57°47′W) is a plateau, 10 nautical miles (19 km; 12 mi) long and from 1 to 3 nautical miles (1.9 to 5.6 km; 1.2 to 3.5 mi) wide, rising to 1,035 metres (3,396 ft) between Misty Pass and Theodolite Hill, Trinity Peninsula, Antarctica.
The plateau rises south of Schmidt Peninsula and the Chilean scientific station, Base General Bernardo O'Higgins Riquelme.
Location
Laclavère Plateau is in Graham Land towards the north of the Trinity Peninsula, which forms the tip of the Antarctic Peninsula.
It is southeast of the Huon Bay, south of the Duroch Islands and Schmidt Peninsula, west of the Mott Snowfield and Duse Bay and north of Broad Valley.
Named features include Misty Pass in the west and Theodolite Hill in the east.
Name
Laclavère Plateau was named by the UK Antarctic Place-Names Committee (UK-APC; 1963) after French cartographer Georges R. Laclavère, President of the Scientific Committee on Antarctic Research (SCAR), 1958–63.
Features
Named features, from west to east, include:
Misty Pass
63°29′S 57°59′W.
A pass, 700 metres (2,300 ft) high, between the head of Broad Valley and a valley descending north to Bransfield Strait, situated 8 nautical miles (15 km; 9.2 mi) southeast of Cape Ducorps.
Mapped by the Falkland Islands Dependencies Survey (FIDS) in 1946, and so named because clouds pouring east through the pass had been noted by the survey party to herald bad weather.
Prilep Knoll
63°29′15″S 57°58′45″W
An ice-covered hill rising to 713 metres (2,339 ft).
Situated at the south entrance to Misty Pass west of Laclavère Plateau, 2.39 kilometres (1.49 mi) east of Morro del Paso Peak, 1.41 kilometres (0.88 mi) south by west of Dabnik Peak, 10.08 kilometres (6.26 mi) west of Kanitz Nunatak and 6.72 kilometres (4.18 mi) north of Yarlovo Nunatak.
This brief starts where responsible research should: with the source description of “Laclavère Plateau” as plateau in Antarctica. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as plateau in Antarctica. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Feb 27, 2026. The linked authority identifier is Q6468743. Authority coordinates are -63.450, -57.783. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1963, 1958 and 1946.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
