Response of North American ice sheets to the Younger Dryas cold reversal (12.9 to 11.7 ka)
Abstract The Younger Dryas (YD; 12.9 to 11.7 thousand years before present [ka]) was an
abrupt cooling event in the North Atlantic region that interrupted the last deglaciation. This …

Rock avalanches in northeastern Baffin Island, Canada: understanding low occurrence amid high hazard potential
Rock avalanches in fjord environments can cause direct catastrophic damage and trigger
secondary submarine landslides and tsunamis. These are well-documented in Greenland …

Unravelling the fragmented sediment–landform assemblage in an area of thick Quaternary sediment, western Hudson Bay Lowland, Canada
Laurentide Ice Sheet (LIS) reconstructions beyond the last glacial maximum (LGM) are
difficult due to the incomplete stratigraphic record that has largely been eroded by the most …

South-central Laurentide Ice Sheet dynamics and the formation of proglacial Lake Vita during MIS 3
An understanding of the growth and demise of ice sheets over North America is essential to
inform future climate models. One poorly studied subject is the glacial dynamics during …

Boreal forest cover was reduced in the mid-Holocene with warming and recurring wildfires
The hemi-boreal zone, marking North America's southern boreal forest boundary, has
evolved post-glaciation, hosting diverse ecosystems including mixed forests with savannas …

Last ice sheet recession and landscape emergence above sea level in east-central Sweden, evaluated using in situ cosmogenic C from quartz
In situ cosmogenic 14 C (in situ 14 C) in quartz provides a recently developed tool to date
exposure of bedrock surfaces of up to∼ 25 000 years. From outcrops located in east-central …

Shifting sediment depocenters track ice-margin retreat in Baffin Bay
Reconstructing the depositional history of Baffin Bay allows insights into the deglacial retreat
of the Laurentide, Innuitian, and Greenland ice sheets from their maximum extent during the …

Stemmed points and the ice-free corridor
JW Ives - PaleoAmerica, 2024 - Taylor & Francis
Fluting or basal thinning of lanceolate points can be readily recognized, so that much
reasoning about the initial occupation of the Ice-Free Corridor has centered on the fluted …
