Steve Mrozowski talking about Sylvester Manor on Here and Now on WABC

On Feb 14 the Fiske Center’s Steve Mrozowski, along with Dr. Georgette Grier-Key of the Eastville Community Historical Society, were featured in a segment of Here and Now talking about Sylvester Mannor. The show was hosted by Emmy Award winning  journalist Sandra Bookman.  Here and Now is a  weekly one hour program,  that is dedicated to covering the issues and interests of the African-American community in the New York tri-state area.  The video clip is about 8 minutes long.

Alice Fiske, our benefactor, contributed to the understanding of slave life in colonial New York by opening her 350-year-old  Sylvester Manor estate on Shelter Island to archaeological study by Steve Mrozowski and UMass Boston.  She died at at the Manor, on April 17 2006 at the age of 88.

Sylvester Manor Cemetery Survey: What were we looking for?

If you’ve been following the blog lately, you may have seen several posts relating to our recent work at Sylvester Manor. Located on Shelter Island, New York, this site has deep connections with the Fiske Center. In mid-March, a team from UMass Boston spent several days conducting a small geophysical survey on the grounds of the manor.

Steve Mrozowski (right, foreground) and John Steinberg take the GPR unit on a test run before beginning a full survey. John Schoenfelder (background) maps the area.

The original multi-year research project at Sylvester Manor was concerned with understanding the interrelationships of the various groups of people who interacted at the site in the 1600s and 1700s, including Anglo-Dutch colonists, enslaved Africans, and Native American laborers. These peoples’ presence was known from historic documents, although not all of them left their own writings. What is clear from this and the archaeological findings are that the interactions among all of these people changed them and their cultures in profound ways. However, it is often difficult to tease out these specific influences from the artifacts alone (Mrozowski et al. 2007:2-8).

One particular location on the manor’s grounds where these kinds of changes may be more visible is the area said to be the manor’s slave cemetery. Since the late 19th century, a memorial has stood commemorating the “Burial Ground for the Colored People of Sylvester Manor.” This memorial and local lore attest to the idea that this place was where the plantation’s slaves were being buried, as early as the 1600s. Although a fence marks off its location from the surrounding low hills, and some small rocks dot the area like grave markers, it is not possible to confirm or deny the story just by looking at the ground’s surface. Out of respect for the dead and respect for any living descendants, as well as in accordance with various laws and good archaeological practice, Fiske Center researchers planned no excavations of the cemetery grounds to try to answer this question.

In order to see if the area holds any burials, the team (including Drs. Steve Mrozowski, John Steinberg, and John Schoenfelder, as well as three UMass Boston graduate students) opted to use a shallow geophysical technique called ground-penetrating radar (GPR). GPR works by sending out regular pulses of electromagnetic energy into the ground at a similar frequency to cell phone transmissions. These waves bounce off of different kinds of surfaces underground, such as geological layers, rocks, or buried human-made features like foundations and graves. The GPR unit receives the reflected waves and produces a radargram, which is read for particular kinds of anomalies. Since these readings are taken in closely-spaced straight lines across the study area, the radargrams produced are then “sliced” so that it’s possible to see what the ground looks like at various depths across the whole area at once. These slices effectively “excavate” the ground at different depths and allow researchers to see the kinds of things that may be found at those depths. (See John Steinberg’s illustration of this, including what archaeologists look for in the radargrams.)

Since other kinds of anomalies, such as tree roots, can sometimes appear like graves, we also collected data in a control area–a second area outside of the fenced cemetery but nearby and still within the same type of natural setting. Even in the field, it was clear that the areas looked very different in terms of the GPR. The types of anomalies seen in the fenced area were not being found outside of it, potentially proving that the cemetery, is, in fact, where it’s said to be.

UMass Boston graduate students Nadia Kline (left) and Allison Conner process GPR data on a day when fieldwork was rained out.

More analysis needs to be conducted in order to draw any definitive conclusions about the data, but the preliminary results suggest the presence of graves within the area known as a burial ground. It is highly unlikely that the GPR alone would be able to show whether the burials are of enslaved persons, but positive geophysical results lend credence to the stories told about this place.

This study marked the first archaeological field research conducted at Sylvester Manor in about five years, and certainly proves that there is always more that places like this can teach us. In this case, finding probable graves within the cemetery reminds us not to dismiss oral histories, but to explore how they bear out under further scrutiny.

Show Celebrates Sylvester Manor: On display at New York University beginning on April 10

Alice Fiske and Stephen Mrozowski

There is a short article in the East Hampton Star about our work at Sylvester Manor and the upcoming exhibition opening at NYU. For some reason the reporter got the impression that there was an NYU group doing work as well.  All the archaeological work at Sylvester Manor during March 2013 was done by The Fiske Center at UMass Boston, including the GPR.  You can see some of the results in a previous post.  NYU does hold the very interesting archives from Sylvester Manor.

Sylvester Manor Cemetery Survey: better preliminary results

A nicer version of the information in the previous post

My good friend Ray Dillman, a graphic artist who makes commercials and such has long lamented the poor training scientists receive in data presentation.  He had some time on his hands and made my screen shot of the GPR look so much better.  Thanks Ray and I hope the fonts in the jpg came out correctly.

If you are interested in learning more Wikipedia has a nice entry on GPR (and the pictures there are not much better than in my previous post).

Ironically we just finished a mini-course at the Fiske Center that was called “Charts, graphs, & tables” that I gave.  Needless to say, the focus was on content.  Maybe I should expand the course to include at least a mention of aesthetics.

Sylvester Manor Cemetery Survey: preliminary results

Split screen of a GPR slice and radargram with one of many potential graves pointed out.

To the left are preliminary images and results of the GPR survey.  Looks like there are multiple graves.  I have pointed out one.  It shows a strong reflector (at the red dot in the upper blue and red image) and has the distinct upside-down “V” associated with features like burials in the lower Radargram image.
