Rivers, lakes and dynamics under the Antarctic ice sheets

I remember when Lake Vostok was discovered 15 years ago, so it's neat to see how this has evolved:

“In the last 15 years, we’ve gone from thinking there’s a little water under ice sheets, to thinking there are lakes the size of New Jersey under ice sheets, to thinking water can move around underneath ice sheets,” Dr. Bell said. “Now, we know that water can modify the basic structure of the ice sheets.”

This is the last frontier of geography, truly the last of the earth to be explored and uncovered.
