Faunal remains from fossil arctic ground squirrel (Urocitellus parryii) middens provide insight into the composition of small mammal communities during the late Pleistocene of Yukon Territory. We evaluated skeletal remains present in 88 of 249 midden

The shift in climate that occurred between the Last Glacial Maximum (LGM) and the Early Holocene (ca. 18–12 kyr BP) displayed rates of temperature increase similar to present-day warming trends. The most rapid recorded changes in temperature occurr

Traditional precipitation isotope archives (e.g., ice cores) are fundamental to our knowledge of past climate but limited to glaciated locales. Here the authors show that pore ice in relict permafrost holds equal promise as a proxy and use it to prov

A comprehensive map of glacial landforms is presented for the area of northwest Saskatchewan, Canada. Remote sensing of 1-arc (∼30 m resolution) Shuttle Radar Topography Mission digital elevation models over an area of approximately 15,000 km2 were

The climatic transition from the Last Glacial Maximum (LGM) to the early Holocene (ca. 18–12 ka BP) involved rates of temperature change comparable with present-day warming trends. The most rapid recorded changes in temperature occurred during the

Organic matter, upon dissolution into the aqueous state as dissolved organic matter (DOM), can undergo mineralization by microbes. There has been increasing effort to characterize DOM released from thawing permafrost because it may perpetuate a perma

The timing of Laurentide Ice Sheet deglaciation along its southwestern margin controlled the evolution of large glacial lakes and has implications for human migration into the Americas. Accurate reconstruction of the ice sheet's retreat also constrai
