[1] The Koettlitz Glacier appears to have been smaller during the Last Glacial Maximum (LGM) than it is today, while the Ross Ice Shelf was larger.

There is evidence that during the LGM the mouth of the Pyramid Trough was blocked by grounded Ross Sea ice until at least 11,000 years ago.

This is in contrast to the view that glaciers feeding the Ross Sea would have been larger during the LGM due to increased accumulation, and the ice shelf smaller.

It is of major scientific interest due to the unique collection of fish and marine invertebrates on its ablating surface.

A roughly circular névé about 7 nautical miles (13 km; 8.1 mi) wide at the head of Koettlitz Glacier.

Named by US-ACAN in 1963 for Major James Foster, United States Marine Corps (USMC), assistant air operations officer for U.S. Navy Task Force 43 in Antarctica, 1960.

A small alpine glacier occupying a high cirque on the east side of Mount Dromedary in the Royal Society Range.

A meltwater stream from Koettlitz Glacier on the east side of The Bulwark, a mountain outlier south of Walcott Bay, Scott Coast.

The stream flows north and then west, following the perimeter of The Bulwark to enter Trough Lake and the Alph River system.

The portion north of Pyramid Trough was explored and named in February 1911 by the British Antarctic Expedition (BrAE) Western Journey Party led by Thomas Griffith Taylor.

He reported that the stream continues north a considerable distance under moraine and ultimately subglacially beneath Koettlitz Glacier to the Ross Sea.

This led to the name from a passage in Samuel Taylor Coleridge’s poem Kubla Khan: "Where Alph the sacred river ran, Through caverns measureless to man, Down to a sunless sea.

Named by Taylor of the BrAE (1910–13), presumably for Charles Doolittle Walcott, Director of the U.S. Geological Survey (1894–1907) and Secretary of the Smithsonian Institution, 1907–28.

Description: A meltwater stream draining from the north side of Howchin Glacier in Denton Hills, Scott Coast.

So named by the VUWAE, 1960–61, because it was up this glacier that the geologists traversed to the Koettlitz-Skelton divide at the ridge crest in order to gain their only glimpse of the polar plateau in January 1961.

A group of rocks standing below the NW slopes of Mount Morning on the south margin of upper Koettlitz Glacier.

Named by US-ACAN in 1994 after Roger A. Barlow, USGS cartographer, a member of the satellite surveying team at South Pole Station, winter party 1992.

A rocky spur 3 nautical miles (5.6 km; 3.5 mi) long, lying at the south side of Foster Glacier in the Royal Society Range.

An island, 3 nautical miles (5.6 km; 3.5 mi) long and 555 metres (1,821 ft) high, which projects through the ice of the Koettlitz Glacier just east of Walcott Bay.

Discovered and named by the BrNAE (1901–04) for Seaman William L. Heald, a member of the expedition who saved the life of Ferrar when the latter was suffering from scurvy in 1902.

Small, dark cape forming the south side of Salmon Bay on the coast of Victoria Land.
