Marescot Point (63°29′S 58°35′W / 63.483°S 58.583°W) is a small but distinctive low rocky point projecting north from Trinity Peninsula, Antarctica, 2.5 nautical miles (4.6 km; 2.9 mi) east of Thanaron Point.[1]
Location[edit]
Marescot Point is on the north shore of Trinity Peninsula, which itself is the tip of the Antarctic Peninsula. It faces Astrolabe Island in the Bransfield Strait on a relatively straight stretch of coast between Bone Bay to the west and Lafond Bay to the east. The [[Louis Phillippe Plateau is inland, to the south. Inland and coastal features between Bone Bay and Lafond Bay include, from west to east, Hanson Hill, Thanaron Point, Corner Peak, Crown Peak and Marescot Ridge. Offshore features of the coastal stretch include Duparc Rocks, Hombron Rocks and Jacquinot Rocks.[2][3]
Name[edit]
"Marescot Point" is a reidentification of Captain Jules Dumont d'Urville's original "Cap Marescot," named after Jacques Marescot du Thilleul (1808–39), an ensign on the Astrolabe during d'Urville's expedition (1837–40), who died during the voyage.[1]
Nearby features[edit]
Hanson Hill[edit]
63°35′S 58°49′W / 63.583°S 58.817°W. A snow-covered hill 900 metres (3,000 ft) high with two lower summits, one to the north and one to the south, standing 4 nautical miles (7.4 km; 4.6 mi) southeast of Cape Roquemaurel. This hill was roughly charted but left unnamed by the French expedition under Captain Jules Dumont d'Urville in March 1838. In 1948, the UK-APC gave the name "Thanaron Hill" to the feature. Their action followed a 1946 search by the FIDS which failed to identify a coastal point in the vicinity to which d'Urville had given the name "Cap Thanaron." The latter feature (now Thanaron Point) was subsequently identified. In 1963, the UK Antarctic Place-Names Committee (UK-APC) renamed the hill described after Thomas A. Hanson, FIDS surveyor at Hope Bay, 1957-59.[4]
Thanaron Point[edit]
63°30′S 58°40′W / 63.500°S 58.667°W. A rock point 8 nautical miles (15 km; 9.2 mi) east-northeast of Cape Roquemaurel. Named in 1838 by the French expedition under Captain Jules Dumont d'Urville after Lieutenant Charles Thanaron of the expedition ship Zélée. [5]
Corner Peak[edit]
63°35′S 58°39′W / 63.583°S 58.650°W. A pyramidal peak 930 metres (3,050 ft) high with considerable rock exposed on its north face. Located 8 nautical miles (15 km; 9.2 mi) east-southeast of Cape Roquemaurel, it marks a corner in the broad glacial valley which rises immediately to the southeast and fans out northwest to form a piedmont ice sheet on the northwest side of Trinity Peninsula. Named by the Falkland Islands Dependencies Survey (FIDS) following a 1946 survey.[6]
Crown Peak[edit]
63°34′S 58°33′W / 63.567°S 58.550°W. An ice-covered peak 1,185 metres (3,888 ft) high topped by a conspicuous crown-shaped ice formation. It forms the highest summit and the south end of Marescot Ridge and lies 10 nautical miles (19 km; 12 mi) east of Cape Roquemaurel. Named by the FIDS following their survey of the area in 1946.[7]
Marescot Ridge[edit]
63°32′S 58°32′W / 63.533°S 58.533°W. A ridge consisting of numerous ice-covered hills, the highest being Crown Peak 1,185 metres (3,888 ft) high at the south end of the ridge. Located 2 nautical miles (3.7 km; 2.3 mi) inland from Marescot Point along the northwest coast of Trinity Peninsula. This ridge was probably observed by Captain Jules Dumont d'Urville on February 27, 1838, when he named nearby "Cap Marescot" (now Marescot Point). Following its 1946 survey, the FIDS gave the name Marescot Ridge to this ridge, thinking it to be the coastal feature named by d'Urville. The name Marescot has been retained for both the ridge and the nearby point.[1]
Duparc Rocks[edit]
63°31′S 58°50′W / 63.517°S 58.833°W. A group of rocks between 1 and 2 nautical miles (1.9 and 3.7 km; 1.2 and 2.3 mi) off the coast, 3 nautical miles (5.6 km; 3.5 mi) northeast of Cape Roquemaurel. Mapped from surveys by FIDS (1960-61). Named by UK-APC for Louis Duparc, French naval officer on the Astrolabe during her Antarctic voyage (1837–40).[8]
Hombron Rocks[edit]
63°28′S 58°42′W / 63.467°S 58.700°W. Rocks awash lying off Thanaron Point. Discovered by a French expedition, 1837-40, under Captain Jules Dumont d'Urville, and named by him for Jacques Hombron, a surgeon with the expedition. The rocks were surveyed by the FIDS in 1946.[9]
Jacquinot Rocks[edit]
63°26′S 58°24′W / 63.433°S 58.400°W. Group of rocks about midway between Hombron Rocks and Cape Ducorps and 1 nautical mile (1.9 km; 1.2 mi) off the north coast of Trinity Peninsula. Charted in 1946 by the FIDS who named the rocks for Honoré Jacquinot, surgeon with the French expedition under Captain Jules Dumont d'Urville which explored this coast in 1838.[10]
