Kind of like archeology camp for adults. We learned about and helped to excavate a site behind the Masonic Temple on what was  known from the late 1700s as Shuter's Hill. 

The excavation has been going on for years, in part to serve as an educational site. Teams of two each had a "unit," about three feet by four feet, using trowels to scrape down level by level. 

My partner Sheila and I were 7 layers down, finding bits of pottery, animal bones & teeth, a few nails, remnants of brick dust and charcoal. 

After two days of digging, we went to the lab with our artifacts. We washed them, put them on a screen, for later cataloguing and storage.
