GEOGRAPHIC NAMES OF ANTARCTICA 



under Rymill, who used the provisional name 

 Middle Island for this feature. The island was re- 

 surveyed in 1948 by the FIDS and renamed by them 

 for V. Adm. Sir Archibald Day, Hydrographer to the 

 Navy. Not adopted: Middle Island. 



DAYMAN, CAPE: cape which forms the E. side of 

 the entrance to Yule Bay, in Victoria Land; in 

 about 70°40'S., 166°45'E. Disc, in 1841 by a Br. 

 exp. under Ross, who named it for Joseph Dayman, 

 mate on the Erebus. 



DAYNe peak : distinctive pyramidal peak about 

 2,400 ft. in el. rising immediately NE. of Cape 

 Errera, the SW. tip of Wiencke I., in the Palmer 

 Arch.; in 64°54'S., 63°35'W. Disc, by the BelgAE, 

 1897-99, under De Gerlache. Named by the FrAE, 

 1903-5, under Charcot, for Pierre Dayne, mountain 

 guide and member of the expedition. Not adopted : 

 Mount Dayne. 



DEACON, CAPE: ice-covered cape forming the 

 SE. tip of Kemp Pen., on the E. coast of Palmer 

 Pen.; in 73° IT'S., 59°53'W. Probably first seen by 

 members of the USAS who photographed a portion 

 of Kemp Pen. while exploring this coast from the 

 air in December 1940. During 1947 the cape was 

 photographed from the air by members of the 

 RARE, who in conjunction with the FIDS charted 

 it from the ground. Named by the FIDS for George 

 E. R. Deacon, English oceanographer and member 

 of the Discovery Investigations staff, 1927-39, and 

 now Dir. of the National Inst, of Oceanography. 



DEACON HILL: conspicuous, ice-covered peak, 

 rising abruptly above the icecap in NW. Coronation 

 I., in the South Orkney Is.; in 60°34'S., 45°49'W. 

 Named by DI personnel on the Discovery II follow- 

 ing their survey of the South Orkney Is. in 1933, for 

 George E. R. Deacon. 



DEACON PEAK: peak about 600 ft. in el. mark- 

 ing the summit of Penguin I., at the E. side of the 

 entrance to King George Bay, in the South Shet- 

 land Is., in 62°05'S., 57°56'W. Charted and named 

 during 1937 by DI personnel on the Discovery II 

 for George E. R. Deacon. 



Dead Glacier: see Konig Glacier. 



DEAKIN, MOUNT: peak, about 9,100 ft. in el., in 

 the Commonwealth Range, marking the N. side 

 of Keltie Gl. at its confluence with Beardmore Gl.; 

 in about 84°42'S., 171°15'E. Disc, and named by 

 the BrAE, 1907-9, under Shackleton. 



DEAKIN BAY: wide-open bay lying W. of Cape 

 Freshfield along George V Coast; in about 68°25'S., 

 150°30'E. The USEE, 1834-42, under Wilkes, ex- 

 plored this area in December 1840. The Peacock, 



under Capt. William L. Hudson, entered what the 

 USEE thought was a bay, in 65°55'S., 151°18'E., 

 and the bay thus explored was named for the ship 

 Peacock. The mainland of George V Coast was 

 first actually explored by the AAE, 1911-14, under 

 Mawson, when the Eastern Coastal party reached 

 as far as 150°12'E. They named the bay for Sir 

 Alfred Deakin, Australian Prime Minister in 1910. 

 Not adopted: Peacock Bay, Peacocks Bay. 



De Alencar, Mount: see Alencar Peak. 



DfiBARQUEMENT ROCK: ice-free rock marking 

 the N. end of the Dumoulin Its. and the NE. end 

 of Geologic Arch., lying close N. of Astrolabe Glacier 

 Tongue, off Adelie Coast; in 66°36'S., 140°04'E. 

 The Fr. exp. under D'Urville landed on a rocky islet 

 in this vicinity in January 1840 and gave the name 

 "Rocher du Debarquement." Positive identifica- 

 tion of this feature has not been made, but on the 

 basis of aerial photographs taken by USN Op. Hjp., 

 1946-47, and surveys and geological studies made 

 by the FrAE during the 1950-52 period, the seaward 

 position of Debarquement Rock is believed to cor- 

 relate with the feature so named by D'Urville. 



DEBENHAM GLACIER: glacier which flows in 

 an ENE. direction into the N. part of Wilson Pied- 

 mont GL, on the coast of Victoria Land; in about 

 77°07'S., 163°00'E. This feature was indicated on 

 charts of the BrNAE under Scott, 1901-4, and the 

 BrAE, under Shackleton, 1907-9. It was named 

 by the BrAE under Scott, 1910-13, for Frank 

 Debenham, geologist with this exp. and Dir. of the 

 Scott Polar Research Inst., 1925-48. 



DEBENHAM ISLANDS: group of islets and rocks 

 lying between Millerand I. and the W. coast of 

 Palmer Pen.; in 68°08'S., 67°07'W. Disc, and 

 named by the BGLE, 1934-37, under Rymill; the 

 exp. base was on Barry I., in the center of the 

 group, during part of this time. Named for Frank 

 Debenham, who served as member of the BGLE 

 Advisory Committee. 



DeBusk, Mount: see DeBusk Scarp. 



DeBUSK SCARP: nearly vertical rock cliff, about 

 1,000 ft. in el., at the S. side of the mouth of Bing- 

 ham Gl., on the E. coast of Palmer Pen.; in 69°23'S., 

 62°57'W. This feature was photographed from the 

 air in 1928 by Sir Hubert Wilkins, and again in 

 1940 by members of the USAS who also sledge sur- 

 veyed along this coast. It was resighted by the 

 RARE, 1947-48, under Ronne, who named it for 

 Clarence DeBusk, executive secretary of the Cham- 

 ber of Commerce, Beaumont, Texas, who was of as- 

 sistance to the RARE in the preparation for the 

 voyage south. Not adopted: Mount DeBusk.
