The idea is to isolate the modern layers closer to the surface, so that they're better able to recognize layers from Jefferson's time.

"So, figuring that out depends on being able to identify, you know, a change in the color or texture of the sediment that would demarcate where we have a deposit of dirt and then a later, different looking dirt on top of it," explained Director of Archaeology at Monticello Fraser D. Neiman.
The project is one of several to restore a mountain-top area adjacent to the historic mansion, which was a street where Jefferson's slaves lived and worked.
UVA archaeologists say they're working to make the landscape of slavery more visible and understandable.
