In this interactive map, you can explore all the glacial landforms and chronologies that were used to generate the new reconstructions of the last Patagonian Ice Sheet from 35,000 years ago to the present day.
The GIF below shows the extent of the ice sheet in 5000 year timeslices. The colours around the margin show where we have high, medium and low confidence in where we have placed the margin.
The image below shows the evidence used to create the reconstruction. You can explore this data yourself using our interactive map that uses ArcGIS Online.
