Kirwan Escarpment
From Wikipedia, the free encyclopedia
Kirwan Escarpment () is a prominent northwest-facing escarpment which lies south of the Penck Trough in Queen Maud Land. The escarpment is featured by moderate-height cliffs and prominent rock spurs interspersed with glaciers and steep ice slopes and trends NE-SW for about 90 miles. At least the northern end of this feature (Neumayer Cliffs) was included in the aerial photography of the general area by the 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.
