Black Glacier
Black Glacier () is a broad tributary to the Lillie Glacier flowing northeast, marking the southeast extent of the Bowers Mountains, a major mountain range situated in the geographical location of Victoria Land, Antarctica. The glacier was first mapped by the United States Geological Survey from ground surveys and from U.S. Navy air photos, 1960–62, and named by the Advisory Committee on Antarctic Names for Robert F. Black, former geologist of the University of Wisconsin, project leader for Antarctic patterned ground studies, who carried out research in
Eocene–Oligocene extinction event). The term Late Cenozoic Ice Age is used to include this early phase.
During this last glacial period there were alternating episodes of glacier advance and retreat. Within the last glacial period the Last Glacial Maximum was approximately 22,000 years ago. While the general pattern of global cooling and glacier advance was similar, local differences in the development of glacier advance and retreat make it difficult to compare the details from continent to continent (see picture of ice core data below for differences).
