COMPOSITE GAZETTEER OF ANTARCTICA

N-most point of Trinity Peninsula, was roughly charted by FAE, 1837-40, in February 1838, when the name Cap Siffrey was applied to the point 5 km to the E (Siffrey Point, q.v.). Following survey by FIDS from "Hope Bay" in 1946, the name Cape Siffrey was erroneously applied to the present feature (BA chart 3205, 23.ix.1949; APC, 1955, p.19). Cabo Siffrey (Chile. DNH chart L, 1951; Pierrou, 1970, p.560; Chile. IHA, 1974, p.260). Mys Sifre (Soviet Union. MM chart, 1961). Following air photography by FIDASE, 1956-57, and detailed study of FAE records, Siffrey Point was identified as the feature originally named by FAE, and the present feature was renamed Prime Head in reference to its being the N-most point of the peninsula (APC, 1964, p.4; BAS 250 sheet SP 21-22/13, 1-DOS 1974). Mys Praym (Soviet Union. AA, 1966, Pl. 24).

Prominent snow-covered headland which forms the N extremity of Antarctic Peninsula. The name Siffrey was given to a cape in this vicinity by the French expedition under Capt. Jules Dumont d'Urville, 1837-40, and was previously approved for the feature here described. D'Urville's "Cap Siffrey" has since been identified by the UK-APC as a point 2 mi to the ESE, now called Siffrey Point. The name Prime Head, given by the UK-APC in 1963, alludes to the position of the headland as the first or northernmost feature of Antarctic Peninsula.

Fue descubierto y denominado por la Expedición Francesa de 1837-1840, al mando de D'Urville. Se encuentra a 6 millas al NW del monte Bransfield, constituye la punta más avanzada hacia el norte de la península Luis Felipe. El cabo está constituido por un acantilado de hielo de unos 50 mts. de altura.
