The Laurentide ice sheet was the last continental glacier to advance across New England during the Pleistocene Epoch. Short Description. A major recurring glacier that at its maximum completely covered North America east of the Rockies from the Arctic Ocean to a line passing through the.

After 20 000 years ago, Earth started to warm, the Laurentide Ice Sheet began to disappear.
At the LGM 500 feet) above sea level in central Canada , the modeled Laurentide Ice sheet maximum elevation is about 3500 meters ( 11 its southern limit extends to the midwestern U. 1) ( Dorale et al. Because most of the marginal environments of the Cordilleran ice sheet were not conducive to preserving an extensive depositional record access unencumbered, much of our understanding of laurentide this ice sheet has come from limited areas where preser- vation is good notably. ) is critical for understanding glacial growth toward the Last Glacial Maximum ( LGM) refining sea- level histories, studying the Earth system response to laurentide rapid climate change events.
