They found exactly what they were looking for on the first day of their dig.
They located a trench where they believe the first log was laid to build Washington's dining cabin where he held his most important meetings with Army officers over dinner.
It's believed that General Washington had a log cabin constructed to ease the cramped conditions where his aides, servants and wife, Martha all lived and worked during his 6-month Revolutionary War encampment.
"In March of 1778, Martha Washington wrote a letter to her friend Mercy Otis Warren where she said that the General has had a log cabin built to dine and it had made there quarter much more tolerable," archaeologist Joe Blondino said.
There have been many volunteers on site, helping sift soil and search for artifacts including 12-year-old Grace Heffner.
"We're just sifting dirt and getting all the bits and pieces out," Grace said.
Pottery, ammunition, even teeth are among the items found and described to tour groups.
"Most people have never had the chance to visit an active archaeological site, much less one where the archaeologist will stop working and talk to them, but we are more than happy to do that," Blondino said.
The field work portion of the project will end next week. Archeologists will then analyze and catalog all the artifacts and complete a report on their findings. Collectively, they should tell us a lot about the Continental Army's stay at Valley Forge
