Location	Trinity Peninsula, Graham Land

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

Trinity Peninsula, Antarctic Peninsula. Laclavère Plateau towards northeast end

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.

Situated 8.43 kilometres (5.24 mi) south of Ami Boué Peak, 9.81 kilometres (6.10 mi) east-southeast of Dabnik Peak, 6.15 kilometres (3.82 mi) north of Cain Nunatak and 9.84 kilometres (6.11 mi) west by south of Theodolite Hill. Overlooking Broad Valley to the S. German-British mapping in 1996.

Theodolite Hill

63°29′S 57°35′W.

Discovered by the FIDS, 1946, and so named during their survey of the area because it served as an important theodolite station.

Urguri Nunatak

63°26′28″S 57°34′10″W. A rocky hill rising to 560 metres (1,840 ft).
