When it comes to soil analysis, Dr. John Wah loves getting his hands dirty. Deep in a soil pit near the University of Maryland, John shows us how the color and texture of soil can reveal the age of an archaeological site. He works quickly as the sun begins to set in Maryland, but he doesn't forget to mention how much he loves this job.
