The effect of an ice shelf like this disappearing is that glaciers that were held back by it start to side faster into the ocean.

A prominent rocky bluff extending from the coast to 2 nautical miles (3.7 km; 2.3 mi), between Larsen Inlet and Longing Gap.

Named by the UK Antarctic Place-Names Committee (UK-APC) after the buff-colored quartz-plagioclase-porphyry rock which is characteristic of this exposure.

A cluster of four gable-shaped nunataks rising to about 400 metres (1,300 ft) high between Porphyry Bluff and Tower Peak.

So named by UK-APC following British Antarctic Survey (BAS) geological work, 1978–79, from the windscoops associated with each nunatak.

A peak, 855 metres (2,805 ft) high, whose rock exposure stands out clearly from an evenly contoured icefield 5 nautical miles (9.3 km; 5.8 mi) northwest of Longing Gap.

A distinctive rock mountain mass 9 nautical miles (17 km; 10 mi) northwest of Longing Gap, overlooking Larsen Inlet.

A mountain topped by a snow peak, 4 nautical miles (7.4 km; 4.6 mi) east of the northeast corner of Larsen Inlet.

A deeply entrenched narrow glacier on the east side of Wolseley Buttress flowing southward from Detroit Plateau.

Named by UK-APC for Geoffrey Pyke (1894-1948), English scientist who in 1941 originated the ideas developed by the Studebaker Corporation into the M-29 Tracked Cargo Carrier or "Weasel," the first really successful snow vehicle.

An ice-covered peak rising to 1,250 metres (4,100 ft) high in the southeast foothills of Detroit Plateau.

An ice-covered peak rising to 1,302 metres (4,272 ft)[19] high in the southeast foothills of Detroit Plateau.

A glacier 5 nautical miles (9.3 km; 5.8 mi) long close west of Mount Hornsby, flowing south from Detroit Plateau into the ice piedmont north of Larsen Inlet.

A conspicuous steep-sided peak at the northwest corner of Larsen Inlet, immediately north of Muskeg Gap.

A rocky peak rising to 819 metres (2,687 ft)[23] high at the northwest coast of Larsen Inlet.

Situated west of the lower course of Albone Glacier, 6.1 kilometres (3.8 mi) north by east of Cletrac Peak.

A high buttress on the southern edge of Detroit Plateau, forming the west side of Albone Glacier.
