GEOGRAPHIC NAMES OF ANTARCTICA 



DUMBBELL ISLET: low rocky islet lying about 

 1 mi. W. of Alamode I. in the Terra Firma Is., off 

 the W. coast of Palmer Pen.; in 68°43'S., 67°35'W. 

 The islet was surveyed in 1948 by the FIDS, who so 

 named it because of its shape. 



Dumoulin, lies; Dumoulin Islet: see Dumoulin 

 Rock. 



DUMOULIN ISLETS : small group of rocky islets 

 at the NE. end of the Geologie Arch., lying about 

 2.5 mi. N. of Astrolabe Glacier Tongue, off Adelie 

 Coast; in 66°37'S., 140°04'E. A Fr. exp. under 

 D'Urville landed on one of these islets in 1840. The 

 islets were roughly charted by the AAE, 1911-14, 

 under Mawson, who named them after C. A. Vin- 

 cendon-Dumoulin of the Fr. exp., who conducted 

 observations on terrestrial magnetism in that local- 

 ity. The group was photographed from the air by 

 USN Op. Hjp., 1946-47, and recharted by the FrAE 

 under Liotard, 1940-51. 



DUMOULIN ROCK: rock about 1.5 mi. N. of Cape 

 Leguillou, the N. tip of Tower I., lying in Bransfield 

 Str. about 22 mi. W. of Cape Roquemaurel, Louis 

 Philippe Pen.; in 63°30'S., 59°50'W. The Fr. exp. 

 under D'Urville, 1837-40, applied the name lies Du- 

 moulin to what he charted as a small group of islets 

 in this area, but in recent years usage has restricted 

 the name Dumoulin to the single feature described. 

 The name Dumoulin Rock is recommended because 

 of its small size and to avoid confusion with the 

 Dumoulin Islets off Adelie Coast. Named for C. A. 

 Vincendon-Dumoulin, hydrographer with D'Ur- 

 ville's expedition. Not adopted: Dumoulin Islet, 

 lies Dumoulin [French] . 



DUMOUTIER, CAPE: point which forms the S. 

 tip of Tower I., lying in Bransfield Str. about 23 mi. 

 WSW. of Cape Roquemaurel, Louis Philippe Pen.; 

 in 63°35'S., 59°50'W. Named by the Fr. exp., 

 1837-40, under D'Urville, for Pierre Dumoutier, a 

 member of the expedition. 



DUNCAN MOUNTAINS: group of ragged foot- 

 hills rising to peaks about 4,800 ft. in el. and lying 

 just E. of the mouth of Liv GL, fronting on Ross Ice 

 Shelf for a distance of about 18 mi.; centering in 

 about 85°S., 166°W. Disc, by the ByrdAE in No- 

 vember 1929. Named by Byrd for James Duncan, 

 Manager of Tapley, Ltd., shipping agents for the 

 Byrd expedition at Dunedin, New Zealand. Not 

 adopted: James Duncan Mountains.

 in the South Orkney Is.; in 60°44'S., 44°24'W. 

 Sighted on Jan. 12, 1823 by a Br. sealing exp. under 

 Weddell, who named it in honor of the illustrious 

 Dundas family. 



DUNDEE ISLAND: ice-covered island lying E. of 

 the NE. tip of Palmer Pen. and S. of Joinville I.; 

 in 63°30'S., 55°55'W. Disc, and named on Jan. 8, 

 1893, by Capt. Thomas Robertson of the Active for 

 the home port, Dundee, Scotland, from whence the 

 ship sailed in company with three other vessels in 

 search of whales. 



DUNLOP, CAPE: rocky headland about 13 mi. 

 SSE. of Cape Roberts, on the E. coast of Victoria 

 Land; in about 77°12'S., 163°25'E. First charted by 

 the BrAE, 1907-9, under Shackleton, who named 

 this feature Rocky Point. It has since taken its 

 name from Dunlop Island, situated just off this 

 point and named for H. J. L. Dunlop, chief engineer 

 of the exp. ship Nimrod. Not adopted: Dunlop 

 Point, Rocky Point. 



DUNLOP ISLAND: triangular-shaped island, 

 about 1 mi. long and 0.5 mi. wide, which lies along 

 the Wilson Piedmont Gl. of Victoria Land, close 

 NE. of Cape Dunlop; in about 77°12'S., 163°27'E. 

 First charted by the BrAE, 1907-9, under Shackle- 

 ton, who named it for H. J. L. Dunlop, chief engi- 

 neer of the exp. ship Nimrod. Not adopted: Ter-

DURHAM, MOUNT: small mountain about 1,800

 junction of Robert Scott and Leverett Glaciers with 

 the head of the Ross Ice Shelf; in about 85°32'S., 

 151°15'W. Disc, in December 1934 by the ByrdAE 

 geological party under Blackburn, and named for 

 Durham, N.H., the seat of the University of New 

 Hampshire and home of Stuart D. L. Paine, a mem-

DURHAM POINT: the northernmost exposed 

 rock outcrop of Mt. Durham, lying at about 1,100

 the head of the Ross Ice Shelf, in the Queen Maud 

 Range; in about 85°31'S., 151°15'W. Disc, in De- 

 cember 1934 by the ByrdAE geological party under 

 Quin Blackburn, and so named because of its close 

 association with Mt. Durham. 



DURNFORD BLUFF: rounded bluff about 7,020 

 ft. in el., standing behind Cape Douglas on the W. 

 side of Ross Ice Shelf; in about 80°56'S., 159°30'E.
