  • One Man’s Trash is Another Man’s TPQ: Modern Materials in Archaeological Excavations

    Archaeology is trash. There, I said it. Before you call Mr. Jones and have me thrown in a pit of snakes, let me explain. Generally speaking, archaeology focuses on understanding the past through the items that people left behind, i.e., their trash.  Most of the things we find are left around because they were broken or no longer needed. Disposal of these items looked much different before modern garbage collection as we know it today. Rather than trashcans and landfills, trash was often thrown outside of the home or workspace near windows and doors or any other designated disposal areas. These areas, also known as middens, usually have a high number of artifacts and are top-tier when it comes to understanding a site. So, in other words, archaeology is trash, and we love it.

    Most people can get behind the archaeologists saving the trash that’s hundreds or thousands of years old, but things are a little different when it comes to saving more modern materials like plastic.  When visitors or volunteers see things like plastic bottle caps or food wrappers in our bags to bring back to the lab, they usually have a few questions. Like, “Did you mean to keep this?” Or “Why are you keeping this trash?” Here at Ferry Farm, we don’t pick favorites, every bit of trash can tell us something about the site and how it has been used.

    One-way modern materials can help us understand a site is by helping us determine the Terminus Post Quem (TPQ), or “time after which,” of a layer. The TPQ is determined by identifying the earliest production date of the most recently produced item. For layers deposited before the widespread use of plastics, ceramics are usually used for determining the TPQ because they are datable (temporally, not romantically) since most have very specific production dates, and they also hold up pretty well under ground. For example, when looking at the ceramics in a layer with tin-glazed wares, Buckley, and creamware, the TPQ would be 1762 since that is the earliest production date of the most recently produced ceramic (creamware).  All the items in the layer had to have been deposited after that date.

    The same idea works with modern synthetic materials like plastics, which are usually found at sites that have been used within the last 100 years.  If there were to be some plastic soda bottles, weed eater line, and styrofoam in a layer, the TPQ would be 1978. While these materials may also be items you have in your home, not thought to be worth collecting and preserving, their presence in a layer helps provide a date. They can also tell us if an earlier layer was disturbed.

    When archaeologists talk about disturbed layers, we aren’t judging their emotional state or love of 2000s heavy metal.  Instead, when a layer is described as disturbed, that means there was some sort of activity happening after the initial deposition that affected that layer. During last season’s dig, there were layers with a mix of colonial, prehistoric, and modern materials that indicated that the area was disturbed by some subsequent activity. The information gathered by the presence of modern materials is important for the interpretation of the site and its use over time. 

    Example of a disturbed layer– Artifacts include prehistoric flakes and fire-cracked rock, colonial items like tobacco pipe stems, Civil War Minie balls, and modern-day plastics

    Now that we know why we keep this so-called modern trash.  Here are a few examples of how the presence of these items helped our archaeologists understand a part of our site.

    My favorite example happened during last year’s dig. One of our crew, Abbie, was preparing a feature for photographs and had to keep clipping pesky hairlike roots that were in the way. After a bit of excavating, it turns out the “roots” were bristles from a plastic broom. The broom dated the feature fill to the late 20th century and got to the root of the hairy soil issue.

    Our staff has numerous examples of these modern materials being used to help identify previous archaeology as well, from candy wrappers at the bottom of shovel test pits and trenches to an entire trowel! While things like plastic trash bags and food containers aren’t the most exciting to find, they play a part in interpreting the history of activities on the site.

    Once something is left behind, it becomes part of the archaeological record, whether it was 10,000 years ago or yesterday’s lunch.  What does your trash say about you?

  • That’s A Wrap! Ferry Farm’s Dig Season Recap

    October just happens to be Virginia Archaeology Month, and what better way to celebrate than to recap this summer’s excavation at George Washington’s Boyhood Home at Ferry Farm.

    You might remember from our dig preview, that this year’s dig (FF-44) focused on the continued exploration of the 18th-century kitchen site located just northeast of the main house. In 2023, our limited investigations uncovered just a small section of the kitchen’s stone foundation and cellar, giving us a sneak preview of the conditions and parameters of future site work. Armed with this knowledge, our aims this year were to uncover more of the original foundation walls of the kitchen cellar, to uncover additional architectural evidence of the kitchen outbuilding, and explore the surrounding landscape for features. So, did we do it?

    Location of the 18th century kitchen foundation in relation to two later farmhouses dating to 1876 and 1914. 

    We did! But before we get to the fun discoveries, let’s go over how we got there. As far as sites go here at Ferry Farm, this one has been through a lot. Not only did the original 16’ by 16’ kitchen building burn and collapse in on itself in the middle of the 18th century, but it also had two subsequent farmhouses built on top of it that were either moved, damaged in a fire, or demolished all within the last 150 years. A previous archaeology project on the site introduced another element of complexity in understanding the depositional sequence of fills on the earlier 18th-century site, which had obviously been heavily disturbed by all these later events.

    All this led to an interesting excavation. Since a significant portion of the site had previously been excavated in the 1990s, a sizable amount of our site time was spent re-excavating backfilled archaeology units with the purpose of exposing unexcavated layers around the site. Not only would these unexcavated layers allow us to gather new data, but it would also give us the opportunity to better understand the findings as recorded in the earlier reports.

    With the help of our wonderful field school students and interns, we opened a total of twenty-seven 5’x5’ units across the kitchen site. Sifting through the dirt, hundreds of artifacts were found dating to all occupations of Ferry Farm. Super cool finds that date to the 18th-century period of use for the kitchen included tobacco pipe fragments, wine bottle sherds, and a variety of ceramics, including English stoneware, Chinese porcelain, and a German Westerwald ‘GR’ sherd. The prehistoric Native American occupations of the site were represented by an unusually high number of projectile points found (8 and counting!), dating to both the Early Archaic (8000 BC – 6500 BC) and Early Woodland (1100 BC – 500 BC) periods.  Civil War bullets came up in our screens, of course, as did 20th-century plastic, tools, toys, and bottle caps.

    But when it comes to finds, our most exciting discovery did not turn up in our sifting screens.  In fact, it was discovering that the western foundation wall of the kitchen cellar, thought to have been demolished, still survived!  During the 1990s excavations, the archaeologists did not see this portion of the stone foundation and assumed the construction of the 1914 Colbert house had destroyed it. Fortunately for us, it was hiding under a 20th century utility pipe and trench and lay directly adjacent to the Colbert concrete foundation. Now we have all four foundation walls that we hope to fully uncover next year.

    Exposed south and west stone walls of the colonial kitchen lie adjacent to and just outside of the 1914 concrete foundation wall.

    Our excavation units surrounding the kitchen foundation have not, as of yet, exposed additional building features associated with the kitchen outbuilding, such as foundations or fireplaces. That search will continue next year as we continue taking those units down and expanding our site area. Features exposed in the 1990s dig, but not excavated by them or us, such as possible post holes and trash middens, also await our return in 2025, when we plan on finishing their excavation.

    Each year’s excavation is built on the work accomplished in the previous years.  With the incredible amount of work done this past summer of exposing the original kitchen foundation, as well as the later farmhouse foundations, removing old fill, and opening up the adjacent landscape, we are looking forward to expanding our investigations of the kitchen site next year.  Stay tuned as we unravel the mysteries that are here at Ferry Farm, George Washington’s Boyhood Home.
