Archaeology Along the Patuxent

An archaeological site doesn’t occur in a vacuum, it’s part of a larger landscape. That landscape may include a farmhouse and the surrounding farm buildings and fields, or the larger rural community that the farm was a part of. In a town it includes the houses, businesses, public buildings (schools, etc.) and spaces (such as public squares or parks). What we as the archaeologists excavate and study is generally only a small slice of the larger universe that the site was part of. Regardless of how much of a site we excavate, whether a small sample around the house and yard, or a bigger slice of several town lots, we always have to keep in mind that the site is part of something bigger.

 


An old tenant house and the surrounding archaeological site
were once part of a community of dozens of tenant houses
all located within a mile or so of one another.
They were part of larger farms, some owner occupied, others not.
All of these places were connected by dirt roads that led to the
nearest village with its churches, stores, and school.
This tenant house was not an isolated entity.

Over the past year, when we weren’t busy at the Swan House site, the CCASM volunteers and I have spent some time out along the Patuxent River near Benedict doing pedestrian walkovers of selected areas along the river. The work was funded in part by a grant from the Maryland Heritage Authority. We’re part of the new Southern Maryland National Heritage Area! Last year we concentrated our efforts on an area of about 200 acres that includes shore line, rolling agricultural fields, and wooded uplands. In the process we’ve located ten new sites from different time periods. That’s the thing about a large landscape study, people have been living in Maryland since at least the end of the last Ice Age over 12,000 years ago. That’s a lot of time for people to set up camps, villages, farms, towns, roads, and so on across the area. Sometimes the sites are on top of older sites so you get a palimpsest of occupations.

Enslaved men and women labored here in the 18th and 19th centuries
and tenant farms continued to work the land after the Civil War.
And, there were Native Americans living here 1000s of years ago.

One of the things we enjoyed doing on a hot summer day was walking along the shoreline of the river and creeks looking for sites along the banks and in the shallow water. We located a few Native American sites, primarily small shell midden sites of unknown date. Midden is the word archaeologists use to describe refuse or garbage areas. These aren’t the living quarters, but were the areas where people cleaned fish and opened oysters for the cooking pots. You really don’t want a lot of smelly fish guts and sharp oyster shells next to the area where you’re sleeping, so these were near, but not in the camp or village.

We included Charles County’s Maxwell Hall Park within our survey universe. Last fall we placed a series of shovel test pits and a small unit at the mansion house. Shovel test pits or STPs, are small holes, about 18 inches in diameter, that are dug at set intervals across a site to get a look at the soil strata (multiple layers of soil) that are present at that location. This gives us an idea of what kind of soil strata are on a site. Are they undisturbed layers? Were they redeposited from elsewhere? What type of soil are we dealing with – organic loam, silt, sand, clay, or mixtures of these? Is it water deposited (alluvium), erosional deposit (colluvium) washed down a slope, wind deposited (aeolian), or something else (such as redeposited fill)? The STP can be a few inches deep, or up to 3 feet in depth – which is far as you can comfortably drop with a shovel in an 18-inch wide hole, below that you need to start digging bigger units.

STPs also enable us to retrieve artifacts from a location. Theoretically by mapping out the pattern of STPs that have artifacts, as opposed to those that don’t, we can locate the edges of the site. I say theoretically because it all depends on the spacing between the STPs. If you dig a STP every 50 feet, you might get a different result than those placed at 20 feet. But overall, it does give you an idea of how big the site is and where the concentrations of artifacts are.

At the mansion we found a layer of oyster shells that turned out to be a former drive into the property – it was identified as such by Peter Swann, who lived in the house when he was a child. Unfortunately we didn’t find any intact deposits associated with George Maxwell and his family or with the enslaved people who lived and worked there during the 18th and 19th centuries. We plan to broaden our search at the mansion house next spring.

In another part of the survey universe we found two sunken roads. A sunken road is one that has worn a trench into the landscape due to decades of wagon traffic. They often appear on inclines where the wear and tear of horses, wagons, carts, and later early automobiles, caused the soil to erode down the slope. One of the two roads we found may have been used by the British during the War of 1812 when they marched on Washington, D.C. This road runs from my friend Franklin’s farm, up a high ridge and joins the main road toward Washington.

For those of you who don’t know the story, the British made life in Benedict hellish during the summer of 1814. They raided the town on June 15th and stole tobacco from the warehouse. They tried to raid the town again on the 21st, but by that time the Maryland militia had arrived and they were driven off but not before they had done substantial damage to the town. An account in the Pennsylvania Gazette on June 29th noted that “Scarcely a building escaped without injury.”

Then, on 20 August, the British returned and landed British troops at Benedict and camped on Clement Dorsey’s farm. From Benedict, the British marched overland to Washington, D.C. They engaged the American forces at Bladensburg on 24 August, a battle that was not our finest hour. The retreat of the Americans from Bladensburg was called the “Bladensburg Races” because our forces basically ran for it. The Brits continued on to Washington, set the White House and Capitol on fire, as well as some other public buildings and bridges. The Americans set the Navy Yards along the Anacostia River on fire to prevent the British from taking a couple of ships on the ways that were ready to be launched. After wreaking havoc on Washington, the British returned to Benedict, boarded their ships and left.

As we move forward in time, at least three of the sites we found are associated with tenants who lived on the land after the Civil War. Two of them are represented by poured concrete foundations. We’ve mapped the foundations of one building and will be returning to map the other set when the vegetation dies back.

This month, we spent a few days at a shell midden site and placed 31 STPs across the site at 20-foot intervals. We were able to trace the midden location and then found a scattering of artifacts that overlaps with the edge of another site set back from the river. We located the latter last fall and need to do a surface collection once the soybeans are harvested. However, preliminary results suggest that the shell midden dates to at least the Middle Woodland Period, or about A.D. 200 through 950. We just finished the STPs and have a lot of shell and other artifacts to clean and catalog.

I’ll post more about the landscape study as we continue our survey work. Over the next couple of months we’ll be back and forth between the Patuxent River survey, finishing up loose ends at the Swann Site in Port Tobacco, and of course in the Port Tobacco lab cleaning artifacts. And, we are looking for some volunteers! So let me know if you’re interested in joining us.
