Guard Glacier
Guard Glacier () is a broad tributary glacier that drains east along the southern margin of Parmelee Massif to join Murrish Glacier, on the east side of Palmer Land, Antarctica. It was mapped by the United States Geological Survey in 1974, and was named by the Advisory Committee on Antarctic Names for Charles L. Guard, a United States Antarctic Research Program biologist who (with David E. Murrish) made investigations of peripheral vascular control mechanisms in birds in the Antarctic Peninsula region for three seasons, 1972–75.
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).
