February 22-26 under a contract with Charles County, Dr. Tim Horsley of Horsley Archaeological Prospection, LLC investigated parts of Port Tobacco using geophysical methods. This was a professional project but CCASM members were able to help lay in lines and get a chance to experience what was involved.

The magnetometry survey was completed the first day. (It was a long day.) The area being investigated included the front yard of Stagg Hall as well as the lot across the street to the south. As you can see even the road between was investigated.
It took three days to complete the ground penetrating radar (GPR) survey - mainly because of the rain. There were two half days when the rain called a halt to things.
And we also had to deal with the wind. In addition to making us cold, it kept blowing the tape on the road. But we came up with a way to keep the lines on the road straight.
Now we just have to wait for the report. It won't have all the answers, but it will give us a lot of clues to what is happening in the ground.
CCASM members that helped included Mary, Evelyn, Denise, and Carol. And Charles County Archaeologist Esther Read was in charge.
On March 7 Jim Gibb returned to the site and used his transit to obtain the coordinates for the various points that Tim had identified with yellow plastic stakes and flags. Mary assisted him by holding the stadia rod.
