Narrative

off Cape Legoupil, Trinity Peninsula (including all the islands from Wisconsin Islands in the NE to Estay Rock in the SW, but not Demas Rocks), were roughly charted by FAE, 1837-40, during two approaches to the coast on 27-28 February 1838. There was a plotting error in the track of one of these two approaches resulting in the duplication of a length of coastline of c. 13' of longitude in extent, between Gourdin Island and Cape Ducorps. For this reason, between Siffrey Point and Coupvent Point, a single series of features appeared twice on the original chart and were named twice (d'Urville, 1838, map following p.1170). It is now clear that the names Roche Lafarge and Roche Coupvent both refer to the feature now named Lafarge Rocks (q.v.), and the names Île Casy and Roche Duroch to Casy Island (q.v.). Formerly, however, because of a W-ward error in plotting, the names Roche Coupvent and Roche Duroch were identified with individual islands of the present group. This entry lists synonyms that undoubtedly apply to the group, together with those that have been incorrectly thought to apply to it or part of it. Roche Coupvent (d'Urville, 1838, map following p.1170; Vincendon-Dumoulin, atlas, 1847, Pl. 8). Roche Duroch, after Lieut. de Vaisseau Joseph-Antoine Duroch (b. 1812), of the French Navy, an officer in Astrolabe of FAE (d'Urville, 1838, map following p.1170; Vincendon-Dumoulin, 1838, p.8). Roca Coupvent (Spain. DH chart 458, 1861). Roca Duroch (Spain. DH chart 458, 1861; Chile. IHA, 1974, p.108). Coupvent Rock, Duroch Rock (BA chart 3205, 1.vi.1901; BA, 1948, p.185). Isla Duroch (Riso Patron S., 1908, end map). Kap Duroch (Nordenskjöld, 1911b, p.75). Rocher Coupvent, Rocher Duroch (Charcot, 1912, Pl. 1). Coupvent Skj. (HA chart, 1928). Durock [sic] Rock (USHO, 1943, p.109). The islands were surveyed by FIDS from "Hope Bay" in 1946. Duroch Islets (BA chart 3205, 23.ix.1949; APC, 1955, p.9). Islotes Duroch (Argentina. MM, 1953, p.242; Pierrou, 1970, p.329). Rocas Duroch y Coupvent, referring to rejected names (Argentina. MM, 1953, p.331). The islands were photographed from the air by FIDASE, 1956-57. Islas Duroch (Argentina. MM, 1957a, p.92). Duroch Islands (USOO chart 6650, 1963; APC, 1964, p.3; BAS 250 sheet SP 21-22/13, 1-DOS 1974).
