Abstract The Laurentide Ice Sheet was the largest global ice mass to grow and decay during the last glacial cycle (~ 115 ka to~ 10 ka). Despite its importance for driving major changes …
Archaeologists and researchers in allied fields have long sought to understand human colonization of North America. Questions remain about when and how people migrated …
The evolution of past global ice sheets is highly uncertain. One example is the missing ice problem during the Last Glacial Maximum (LGM, 26 000-19 000 years before present)–an …
" Sometime before 15,000 years ago, a band of hunter-gatherers arrived in Northeast Asia. They continued east, becoming the first people to set foot in the Americas. They soon found …
Future sea-level rise poses an existential threat for many river deltas, yet quantifying the effect of sea-level changes on these coastal landforms remains a challenge. Sea-level …
Little is known about woolly mammoth (Mammuthus primigenius) mobility and range. Here we use high temporal resolution sequential analyses of strontium isotope ratios along an …
The Clovis-first model for the peopling of the Americas by∼ 13.4 ka has long invoked the Ice- Free Corridor (IFC) between the retreating margins of the Cordilleran and Laurentide ice …
A series of publications purport to provide evidence that the Earth was subjected to an extraterrestrial event or events at∼ 12.9 ka creating an environmental cataclysm and the …
The most recent deglaciation of the North American Ice Sheet Complex (NAISC: comprising the Innuitian, Cordilleran, and Laurentide ice sheets) offers a broad perspective from which …
