The range is divided into three main mountain blocks, the major summits in each from north to south being Mounts Faith, Hope and Charity.

[1] The Eternity Range is in northern Palmer Land, between the Weddell Sea to the east and Marguerite Bay to the west.

It is to the east of the Dyer Plateau, southeast of the Bristly Peaks, south of the head of Lurabee Glacier, west of Stefansson Sound and north of the Columbia Mountains.

This complication by Rymill, and uncertainty as to the precise location or extent of Ellsworth's discovery, hindered for a time a resolution of its nomenclature.

[1] A careful study of the original reports, maps and photographs, and comparison with materials from subsequent expeditions such as the Ronne Antarctic Research Expedition (RARE), 1947, and the Falkland Islands Dependencies Survey (FIDS), 1960, has led to the conclusion that the range described comprises at least the core of Ellsworth's Eternity Range and appropriately commemorates his discovery.

A massive mountain rising to 3,239 metres (10,627 ft) high[a], forming the central and highest peak of Eternity Range.

Mountain, 2,225 metres (7,300 ft) high, rising southwest of the head of Anthony Glacier and 11 nautical miles (20 km; 13 mi) west of Mount Bailey, inland from the east coast of Palmer Land.

A mountain, 2,070 metres (6,790 ft) high, standing 12 nautical miles (22 km; 14 mi) east of the north part of the Eternity Range.

This feature lies in the area explored from the air by Sir Hubert Wilkins in 1928 and Lincoln Ellsworth in 1935, but it was first charted by the BGLE in 1936-37.

A conspicuous isolated peak 2,360 metres (7,740 ft) high on the east side of Wakefield Highland, near the head of Lurabee Glacier.
