Postcards from Antarctica
The dry valleys of Antarctica rarely get rain. They're not covered with ice, like most of the rest of the continent. The valleys are desolate and remote, and rarely seen by human eyes.
Over the last month, a team of researches from the University of Minnesota's Antarctic Geospatial Information Center and the Science Museum of Minnesota brought space-age technology to the valleys in an attempt to create accurate maps of one of the planet's last frontiers.
The Science Museum's Patrick Hamilton called MPR regularly from inside the dry valleys and left a series of "postcards". Some of his observations will air on MPR's All Things Considered this week.
Check out photos of the team's expedition to the dry valleys Antarctica.
