From Wikipedia, the free encyclopedia

Mertz Glacier (67°30′S 144°45′E) is a heavily crevassed glacier in Antarctica, about 45 miles long and averaging 20 miles wide. It reaches the sea between Cape De la Motte and Cape Hurley where it continues as a large glacier tongue. The Mertz Glacier Tongue (67°10′S 145°30′E) is about 45 miles long and 25 miles wide.

The glacier was discovered by the Australasian Antarctic Expedition (1911-14) under Douglas Mawson, who named it for Xavier Mertz, a member of the expedition who lost his life on January 7, 1913, on the far-east sledge journey
