Last updated

Neumayer Cliffs (German : Neumayersteilwand, 73°7′S1°45′W / 73.117°S 1.750°W / -73.117; -1.750 ) is a series of abrupt rock cliffs forming the northeast end of Kirwan Escarpment in Queen Maud Land. Discovered by the German Antarctic Expedition under Alfred Ritscher, 1938–39, and named for German geophysicist Georg von Neumayer. Surveyed by the Norwegian-British-Swedish Antarctic Expedition (NBSAE), 1949–52.

Joinville Island group is a group of antarctic islands, lying off the northeastern tip of the Antarctic Peninsula, from which Joinville Island group is separated by the Antarctic Sound.

Mount Hallgren is a mountain, largely ice-covered, with a steep, rocky northern face, situated 27 nautical miles (50 km) southwest of the Neumayer Cliffs in the Kirwan Escarpment, Queen Maud Land, Antarctica. It was mapped by Norwegian cartographers from surveys and air photos by the Norwegian–British–Swedish Antarctic Expedition (1949–1952) and additional air photos (1958–59), and named for Stig E. Hallgren, a photographer with the expedition.

The Kirwan Escarpment is a prominent northwest-facing escarpment which lies south of the Penck Trough in Queen Maud Land, Antarctica. The escarpment is featured by moderate-height cliffs and prominent rock spurs interspersed with glaciers and steep ice slopes and trends northeast–southwest for about 90 nautical miles (170 km). At least the northern end of this feature was included in the aerial photography of the general area by the Third German Antarctic Expedition (1938–39), but the maps resulting from that expedition do not portray the escarpment properly. The escarpment was mapped by Norwegian cartographers from surveys and air photos (1958–59) and named for Laurence P. Kirwan, Director of the Royal Geographical Society.

<span class="mw-page-title-main">Neumayer Channel</span>

Neumayer Channel is a channel 16 miles (26 km) long in a NE-SW direction and about 1.5 miles (2.4 km) wide, separating Anvers Island from Wiencke Island and Doumer Island, in the Palmer Archipelago. The southwest entrance to this channel was seen by Eduard Dallmann, leader of the German 1873-74 expedition, who named it Roosen Channel. The Belgian Antarctic Expedition, 1897–99, under Gerlache, sailed through the channel and named it for Georg von Neumayer. The second name has been approved because of more general usage.

Ulendet Crevasses is a crevasse field about 7 miles (11 km) long in the Jutulstraumen Glacier, about 15 miles (24 km) northeast of Neumayer Cliffs in Queen Maud Land.
