We provide a geomorphological analysis of Cordillera Vilcanota and use morphostratigraphic principles to reconstruct palaeo icefield extent and palaeoglacier readvances, likely during the Antarctic Cold Reversal and Younger Dryas. We find evidence of temperate and polythermal ice margins, with limited glaciofluvial landform generation.

The end of the Little Ice Age (LIA) in the nineteenth century triggered glacial retreat across the Northern Hemisphere, leaving behind sediment-landform assemblages that preserve records of glacier behavior.

Tectonics as a Regulator of Shoreline Retreat and Rocky Coast Evolution Across Timescales
Abstract Rocky coast morphology is shaped by interactions between wave action, sea level, and tectonics over millennial time scales. However, a clear and quantifiable signature of tectonic uplift on decadal to centennial shoreline retreat rates is outstanding.

A Lithospheric Drip Triggered Green and Colorado River Integration
Abstract The integration of the Green and Colorado Rivers shifted the continental drainage divide of North America, marking a key event in the hydrological and biogeographical evolution of the continent. Sedimentological and stratigraphic evidence shows that for integration to occur, the Green River likely cut through the Uinta Mountains between 8 and ...

We present the first comprehensive glacial-landform map of the south Swedish uplands (SSU), deglaciated 15–13 ka ago, using one consistent method and dataset; a Light Detection and Ranging-derived digital elevation model.

Quaternary glaciations in Southern Africa? A “moraine” in the Lesotho highland revisited [PDF]
Climate records for the Last Glacial Maximum (LGM) in Southern Africa are scarce, and the glaciation of the highest summits has been controversially discussed.

A Younger Dryas plateau icefield in the Monadhliath, Scotland, and implications for regional palaeoclimate [PDF]
A record of Younger Dryas glaciation in Scotland is well established. However, the role of the Monadhliath, a significant plateau area extending over 840 km2 in central Scotland, has never been investigated systematically. We present the first systematic

Regional landform thresholds [PDF]
Remote sensing technology allows us to recognize manifestations of regional thresholds, especially in the spatial characteristics of process agents. For example, a change in river channel pattern over a short distance reflects a threshold alteration in ...

Soil Organic Matter Stabilization by Polyvalent Cations in a Buried Alkaline Soil
Abstract Buried paleosols can store large quantities of organic carbon (C), much of which persists for millennia due to isolation from surface processes that promote decomposition. Subsoil organic matter (SOM) persistence is often enhanced by mineral associations and ionic conditions—particularly high clay content and polyvalent cations—that limit ...
