Time-Team America in Montgomery County

Time-Team America is a PBS series highlighting  the excavation of different types of American archaeology sites.  In 2012 cameras, archaeology specialists, and university students descended on Josiah Henson Park, formerly known as the "Uncle Tom Cabin" site, for three days.  Members of the ASM Mid-Potomac Chapter helped with the archaeology, mainly behind the scenes.  In the August ASM Ink  Don Housley, the chapter president,  relates what it was like during those three days.

The episode was to air Tuesday August 19 at 8pm on local PBS stations, but I couldn't find it.  I did watch a video of the show at  The Search for Josiah Hansen
