It was named by the UK Antarctic Place-Names Committee (UK-ADC) after John Hadley, an English mathematician who, at the same time as Thomas Godfrey, independently invented the quadrant (the forerunner of the sextant), in 1730–31.

A conspicuous reddish-colored promontory which rises to 690 metres (2,260 ft) high and projects from the west coast of Graham Land between Neny Fjord and Rymill Bay.

Resurveyed in 1948–49 by the FIDS, and so named by them because the col affords a safe sledging route between Neny Fjord and Rymill Bay when there is open water off the west end of Red Rock Ridge.

Mountains rising to 1,370 metres (4,490 ft) high, extending in a west-northwest – east-southeast direction for 5 nautical miles (9.3 km; 5.8 mi) and lying close south of Neny Fjord.

A sharp, pyramid-shaped peak over 1,125 metres (3,691 ft) high, standing in the northwest part of the Blackwall Mountains on the south side of Neny Fjord.

The name was apparently first used by members of the RARE, 1947-48, under Finn Ronne, and the FIDS, and derives from its location near Neny Fjord, and its resemblance to the Swiss Matterhorn.

A mountain, 1,190 metres (3,900 ft) high, with notched and precipitous sides, standing between Romulus Glacier and Bertrand Ice Piedmont.

This mountain lies near the heads of Romulus and Remus Glaciers, and the name derives from the mythological story of the she-wolf which fed these twins after they had been thrown into the Tiber.

A prominent ice-covered mountain 1,845 metres (6,053 ft) high which rises from the northeast part of Hadley Upland and overlooks the head of Gibbs Glacier.

Named by UK-APC after Claudius Ptolemy (2nd century A.D.), Egyptian mathematician, astronomer and geographer, who introduced the system of coordinates of latitude and longitude for fixing positions on the earth's surface.

A glacier-filled valley opening onto the north part of Mikkelsen Bay and providing access via its head to the plateau, Lammers Glacier and the Traffic Circle area.

So named by the BGLE under John Rymill, 1934-37, because of the strong winds which descend from the high plateau and blow out of this valley with great force.
