 close off Adelie Coast; in about 66°38'S., 139°44'E. 

 Photographed from the air by USN Op. Hjp., 1946- 

 47. Charted and named by the FrAE under Lio-

 lie or lies see iinder the specific part of the name. 

 For example for lie Argentines see Argentines, He. 

 {He is a French word for "Island.") 



IL POLO GLACIER: channel glacier about 2 mi. 

 wide and over 8 mi. long, flowing NNE. from the 

 continental ice and terminating at the SE. side 

 of Sandefjord Ice Bay, midway between Polar 

 Times and Polarforschung Glaciers on Ingrid 

 Christensen Coast; in about 69°50'S., 74°15'E. 

 Delineated in 1952 by John H. Roscoe from aerial 

 photographs taken by USN Op. Hjp. in March 

 1947. Named by Roscoe after II Polo, a polar 

 journal published since 1946, by the Institute 

 Geografico at Forh, Italy. 



INACCESSIBLE ISLAND: island about 0.75 mi. 

 long, which is the northernmost of the Dellbridge 

 Is.; lying 1.5 mi. SSW. of Cape Evans, Ross I.; in 

 about 77°40'S., 166°22'E. Disc, and named by the 

 BrNAE, 1901-4, under Scott. 



INACCESSIBLE ISLANDS: group of small 

 islands ranging from 400 to 700 ft. in el., the 

 westernmost of the South Orkney Is., lying about 

 23 mi. W. of Coronation I.; in 60°34'S., 46°44'W. 

 Disc, in December 1821 by Capt. George PoweU 

 and Capt. Nathaniel Palmer, though it is possible 

 they are the Seal Islands seen by Palmer a year 

 earlier. So named by Powell because of their 

 inaccessibility. 



INDICATOR ISLAND: islet about 200 yards 

 lojig, lying about 250 yards W. of NW. end of 

 Galindez I., in the Argentine Is., off the W. coast 

 of Palmer Pen.; in 65°15'S., 64°17'W. Indicator 

 Island was charted and named in 1935 by the 

 BGLE imder Rymill. A wind sock was erected on 

 this island by the BGLE to indicate wind direction 

 for the expedition's airplane. 



Inexpressible Island: see Oscar Island. 



INEXPRESSIBLE ISLAND: island about 2.5 mi. 

 long and 0.5 mi. wide, forming the W. shore of 

 Evans Cove and lying in the outer edge of the 

 Nansen Sheet along the coast of Victoria Land; 

 in about 74°59'S., 163°42'E. First explored by the 

 Northern Party of the BrAE under Scott, 1910-13. 

 Originally called Southern Foothills, in contra- 

 distinction to the Northern Foothills to the NE., 

 the name "Inexpressible" was applied by the 

 Northern Party after spending a very unpleasant 

 winter on half rations on the island. Not adopted: 

 Oscar Island (q.v.). Southern Foothills. 



INGRAM BAY: shallow indentation in the north- 

 ernmost portion of the Amery Ice Shelf where it 

 separates MacKenzie Bay from Prydz Bay, along 

 Lars Christensen Coast; in about 68°30'S., 72°45'E. 

 The BANZARE under Mawson made an air sur- 

 vey on Feb. 10, 1931, sketching the boundaries of 

 MacKenzie Bay. Probably named for Dr. W. W. 

 Ingram, medical officer and biologist on the expe- 

 dition. 



INGRID, CAPE: conspicuous, dark, rocky prom- 

 ontory separating Sandefjord and Norvegia Bays 

 on the W. coast of Peter I Island; in about 68°49'S., 

 90°44'W. Disc, and named in 1927 by a Nor. exp. 

 under Tofte in the Odd I, a vessel of Lars Christen- 

 sen's whaling fleet. Named for the wife of Lars 

 Christensen, Mrs. Ingrid Christensen. 



INGRID CHRISTENSEN COAST: that portion 

 of the coast of Antarctica extending from Jennings 

 Promontory in about 70°12'S., 71°46'E., to about 

 81°00'E. Disc, by the Nor. exp. under Mikkelsen, 

 who landed in the Vestvold Hills sector of this 

 coast in February 1935. Named for Ingrid 

 Christensen, wife of Lars Christensen, who sailed 

 in Antarctic waters with her husband. A south- 

 west extension of this coast, between Sandefjord 

 Ice Bay and Jennings Promontory, was disc, and 

 photographed from the air by USN Op. Hjp. in 

 March 1947. Not adopted: Ingrid Christensen 

 Land.

INNER HARBOR: small harbor in the Melchior 

 Is., Palmer Arch., formed by the semi-circular 

 arrangement of Lambda, Epsilon, Alpha and Delta 

 Islands; in 64°19'S., 63°00'W. The descriptive 

 name was probably given by DI personnel who 

 roughly surveyed the harbor in 1927. It was sur- 

 veyed by Argentine expeditions in 1942, 1943 and 

 1948. Not adopted: Puerto Interior [Spanish].
