Antarctica

[Maxmars]

I found some old research I had meant to turn onto a thread... I never did... but it still seems what I have might be interesting to some people.

From Ancient Origins.net:  Lifting the Lid on Antarctica: Ancient Landscape Revealed Beneath Antarctica
which cites a paper: An ancient river landscape preserved beneath the East Antarctic Ice Sheet

This article discusses how building upon earlier data and supplemented with their own, they have manage to reveal a topological map of the Antarctic.  They speculate about the many river valleys they appear to have found. 

While I found the text good... the pictures captured my imagination...
