Ozarks at Large for Monday, February 16, 2015

Ahead on this edition of Ozarks at Large, another non-profit organization created to deliver water to rural areas in the Arkansas Ozarks is facing economic difficulties. Plus, recreating tombs carved at Petra nearly 2,000 years ago is not an easy task. So difficult, in fact, it wasn't even attempted until recently. We talk with Tom Paradise, a geosciences professor at the University of Arkansas, how he became part of an ambitious project in the American Southwest that will be the subject of this week's episode of Nova on PBS.
