-
The different parts of the Laurentide Ice Sheet reached their maximum extent between 24 and 21 ky BP [28].
-
During its maximum extent, the Laurentide Ice Sheet was more than twice the size of the Eurasian Ice Sheet.
-
This out-of-phase response may be attributable to the effects of growth of the Cordilleran Ice Sheet, which would have intercepted moisture transport to the interior plains at the expense of the Laurentide Ice Sheet.
-
Paleogeographic data from this interval suggest that the Laurentide Ice Sheet was almost completely gone, with the possible exception of residual ice masses in northern Québec.

Several climate heating episodes between 11,000 and 7,700 years BP are attributed to the catastrophic drainage of Lake Agassiz and the Laurentide glacial lakes in North America.

Similar biomes apparently were extensive south of the Eurasian ice sheets of northern Russia, eastward across Siberia and the exposed seabed to the north, and via Beringia into Alaska and the northern Yukon [29], although they were much more restricted south of the Laurentide Ice Sheet in central and eastern North America [30].

The Laurentide Ice Sheet strongly influenced early Holocene (10,000 – 9,000 years BP) climate in northwestern North America, particularly in downwind areas.
