Advances in large-scale paleogeographic reconstruction define physical and environmental constraints relevant to understanding the timing and character of the first colonization of the Americas during the Late Pleistocene. Diachronic mapping shows continental glaciers coalesced in central Canada during the Last Glacial Maximum (LGM) 20,000–14,000 years ago while unglaciated refugia existed along the Northwest Coast. The Bering Land Bridge connected Asia and North America until about 10,000 years ago when the two continents were separated by rising sea level. This visual analysis from large-scale synthesis of recent geological and environmental research establishes timelines for biotically viable colonization corridors connecting eastern Beringia to southern North America and provides insights into probable Paleoindian origins and subsistence strategies.
