GEOGRAPHIC NAMES OF ANTARCTICA 



HELEN GLACIER TONGUE: glacier tongue, 

 which in February 1947 extended about 7 mi. sea- 

 ward from Helen Gl., along Queen Mary Coast; 

 in about 66°33'S., 93°14'E. Disc, in November 1912 

 by members of the Western Base Party of the AAE 

 under Mawson. The glacier tongue takes its name 

 from Helen Glacier. 



HELEN WASHINGTON, MOUNT: high, ridge- 

 like mountain surmounted by three prominent 

 peaks, standing about 5 mi. SSW. of Mt. Paterson 

 near the S. end of the N. group of Rockefeller Mtns. 

 on Edward VII Pen.; in about 78°05'S., 155°15'W. 

 Disc, on the ByrdAE flight of Feb. 18, 1929, and 

 named by Byrd for Miss Helen A. Washington, niece 

 of R. Adm. Richard E. Byrd, leader of the expe- 

 dition. 



Helen Washington Bay: see Kainan Bay. 



HELLAND-HANSEN SHOULDER: a portion of 

 the steep slopes of the snow-covered western bound- 

 ary of the Mohn Basin, resembling snow-covered 

 ridges, when viewed from the E., which extend for 

 an indefinite extent in a N.-S. direction, on the 

 south polar plateau; centering in about 86°12'S., 

 168°20'W. Disc, in December 1911 on the journey 

 to the South Pole by the Nor. exp. under Amundsen, 

 and named by him for Prof. B. Helland-Hansen, of 

 the University of Oslo. 



Hell Gates: see Morton Strait. 



HELL GATES : chain of islets and rocks extend- 

 ing from Livingston I. to Snow I. across the E. 

 portal of Morton Str., in the South Shetland 

 Islands; in 62°41'S., 61°10'W. Named by early 

 sealers in the area because many lives and ships 

 were lost in navigating the strait. Not adopted: 

 Morton Strait. 



HELLS GATE : a small area on the confluent ice 

 of the Nansen Sheet, marked by glacial moraines, 

 lying between Inexpressible I. and the Northern 

 Foothills and discharging into Evans Cove, along 

 the coast of Victoria Land; in about 74°57'S., 

 163°48'E. Disc, and explored by the Northern 

 Party of the BrAE, 1910-13, who gave the feature 

 its expressive name. 



Helmer Hanssen, Mount: see Breyer, Mount. 



HELMER HANSSEN, MOUNT: ice-covered moun- 

 tain, distinguished by a sharp peak at its S. end, 

 rising from a high land mass W. of Amundsen Gl. 

 in the Queen Maud Range; in about 86°05'S., 

 163°50'W. Disc, in November 1911 by a Nor. exp. 

 under Amundsen on the journey to the South Pole, 

 and named by him for Helmer Hanssen, ice pilot 

 of the exp. and deputy leader of the South Pole 



Party. It was resighted by the ByrdAE on the 

 South Polar Flight of November 1929. On subse- 

 quent charts, however, it was shown as Mount 

 Breyer, and the name Mount Helmer Hanssen mis- 

 applied to an unnamed mountain to the E. disc, by 

 Byrd. The US-ACAN accordingly retains the name 

 Mount Helmer Hanssen for the mountain so named 

 by Amundsen, and applies the name Mount Breyer 

 to the unnamed mountain disc, by Byrd. Not 

 adopted: Mount Breyer (q.v.). 



HENDERSON, MOUNT: massive mountain about 

 3,400 ft. in el., rising through the icecap near the 

 continental margin about 8 mi. NE. of the N. end 

 of the Masson Range, on Mac-Robertson Coast; in 

 about 67°42'S., 63°05'E. Disc, in February 1931 

 by the BANZARE under Mawson. Probably named 

 for Prof. G. C. Henderson of Adelaide, a member of 

 the advisory committee for this exp. and for the 

 AAE, 1911-14. 



HENDERSON, MOUNT: mountain in the S. part 

 of the Britannia Range, about 8,100 ft. in el., lying 

 at the N. side of Barne Inlet, on the W. side of Ross 

 Ice Shelf; in about 80°21'S., 156°15'E. Disc, and 

 named by the BrNAE under Scott, 1901-4. 



HENDERSON ISLAND: ice-covered island about 

 8 mi. long and about 600 ft. in el., lying SE. of 

 Masson I., within the Shackleton Ice Shelf, and 

 about 5 mi. N. of Cape Dovers on Queen Mary 

 Coast; in about 66°23'S., 97°07'E. Disc, in August 

 1912 by the Western Base Party of the AAE under 

 Mawson, and named for Prof. G. C. Henderson of 

 Adelaide. 



HENGIST NUNATAK: isolated flat-topped nuna- 

 tak, more than 2,000 ft. in el., which rises above 

 the Roberts Ice Piedmont, about 10 mi. N. of 

 Mount Calais, in the NE. part of Alexander I Is- 

 land; in 69°00'S., 70°14'W. First seen and pho- 

 tographed from the air in 1936 and 1937 by the 

 BGLE under Rymill. Surveyed from the ground 

 in 1948 by the FIDS. The names for this feature 

 and for the group of nunataks to the north are 

 after the brother chieftains, Hengist and Horsa, 

 who led the first Saxon bands which settled Eng- 

 land in the fifth century. 



HENKES ISLETS: group of snow-covered Islets 

 surrounded by reefs, which fringe the SW. coast of 

 Adelaide I. and extend from Cape Adriasola 15
