The Magellan region was commonly visited by European scientists on their way to and from Antarctica and this led to short reports about glacial features in the area (e.g. The influences of continental glaciation are discernible throughout the New York Bight region. The Quaternary period (from 2.588 ± 0.005 million years ago to the present) has seen the extinctions of numerous predominantly megafaunal species, which have resulted in a collapse in faunal density and diversity and the extinction of key ecological strata across the globe.

T1 - Quaternary Glaciation of the Great Lakes Region: Process, Landforms, Sediments, and Chronology. Radiocarbon dates are available for the wetter parts of the Himalayan- Tibetan region, but most are limited to Holocene proglacial deposits, which poorly define the timing of glaciation (Ro¨thlisberger and Geyh, 1985; Lehmkuhl, 1995, 1997). The Quaternary glaciation began 2.58 million years ago and continues to the present, and is thus the current ice age. It is a digital version of the Minnesota Geological Survey State Map Series Map S-1 (Geologic Map of Minnesota: Quaternary Geology), 1982, by H.C. Hobbs and J.E. This represents a major shift from earlier work whereby many glacial sequences were assumed to have formed during the last cold stage.
