The U.S. Geological Survey is searching for commercially important minerals in southeastern Missouri. But the researchers won't be using any shovels or pick-axes: All the data will be collected from a small, low-flying plane.

The aerial survey is part of an on-going project to study the geology of the St. Francois Mountains.
