Lifting the Lid on Antarctica: Ancient Landscape Revealed Beneath Antarctica

“ The research team, led by Durham University, UK, used satellite data and radio-echo sounding techniques to map a 32,000 km2 area of land underneath the vast ice sheet.
They discovered a landscape that appears to have been formed by rivers at least 14 million years ago and possibly even before the initial growth of the East Antarctic ice around 34 million years ago.
This newly discovered landscape consists of ancient valleys and ridges, not dissimilar in size-and-scale to the glacially-modified landscape of North Wales, UK.
Its existence implies a long-term temperature stability of the ice sheet in the area investigated by the researchers. 
The study has been published in the journal Nature Communications.”
