Figure 1: Key features of the North and South American Cordilleran orogenic belts 5. The response of the forearc orogenic wedge to changes in hinterland elevation depends on sediment volume in the ...

The Cordilleran Ice Sheet covered large parts of North America during the Pleistocene - or last ice age - and was similar in mass to the Greenland Ice Sheet. Previous research estimated that it ...

Fine soil particles once encased in ice were discovered in a cave about 20,000 years after the frozen sheet melted. This sediment is significant both for what it tells us about the past and what it ...

The broadly accepted hypothesis for the development of the segmented Cordilleran orogen above a long-lived eastwardly dipping subduction zone is at odds with many critical observations. In this ...

A new study found that remains of the Cordilleran ice sheet have remained at low elevations as late as 11,000 years ago, but had almost completely melted from higher elevations 14,000 years ago.
