The sediment color and composition of each layer in the samples can show what the past climate was like. Dark, organic ...

Geologists found glacial till as expected, but also found weathering from a separate glacial sediment deposited at an unexpected depth — potential evidence of a previously unknown advance of a ...

The sediments analyzed are between 20,000 and 17,000 years old and were deposited in the cave towards the end of the last ice age. They have remained there untouched to this day.

In the background, vegetation covers the frontal moraine, a glacial sediment deposit marking the glacier's stable position during the pre-industrial period (~1850). The vast area between the current ...
