BURIAL HILL DIG: Can archaeologists solve a 300-year-old mystery by 2020?

BURIAL HILL DIG The Old Colony Memorial (plymouth.wickedlocal.com) had an interesting story about the the work at Plymouth.  If the link goes down, you can see a printed version here.  It is perhaps one of the most detailed stories on the work.   The Author, Frank Mand, is an interesting guy.  He has been taking a photo around Plymouth at sunrise for the last year.

Smithsonian.com article about the excavations at Plymouth

Archaeologists Are Trying To Figure Out Exactly Where Plymouth WThere is a nice article about the work that just finished up at Plymouth in Smithsonian.com.  The article is in the SmartNews series, as part of the interesting pieces on Exploring the American Experience.  The author, Marty Beth Griggs, is a  good science writer.  If the link goes down, you can get a pdf here.

Despite threat of poison ivy, the search for Deb Newman continues undeterred

After adjusting our strategy for the remainder of the season, our STP survey took us across the street, where the foundation of Lewis Ellis’s home beckoned through the poison ivy. Drs. Trigg and Bolender, Sam, and myself faced the task of marking off the STPs without getting poison ivy on the tapes or ourselves. In an ideal world this would be possible with the aid of a Total Station- our particular model can find the stadia rod all on its own, with minimal human prodding- but with our line of sight blocked by the trees we did it the old-fashioned way, by pacing off every 10 M with tapes. Naturally this entailed dragging them straight through poison ivy, which is why the tapes are now stored in their own bag in a separate bucket until we clean the equipment at the end of the project.

Back across the street we have officially designated the area around the “barn” as a brand new site because the area doesn’t fall into either of the 1727 allotments of either Deb Newman and Lewis Ellis. Other potential uses for the enclosure include a meeting-house or schoolhouse for the seven Nipmuc families at Hassanamesit in the 18th century, making it even more important that any units dug in this area be given a separate designation in our records.
Dr. Trigg has begun coring inside the enclosure to find the best places for taking soil samples. Like the phosphate analysis she will conduct for the lambing pen, testing these samples will help us narrow down the possible uses for the enclosure.

How do we know where to dig?

Good question. Luckily, historical archaeologists have a lot of resources to help us out. Long before the team opened excavations on the perimeter of Burial Hill, we collected old maps and conducted geophysical surveys to help us determine the precise coordinates of each excavation unit.

The historical record suggests that the first Plymouth Colony fort was located at the top of Burial Hill and the palisade walls ran down the slope of the hill. According to early accounts, the walls of the fort were diamond shaped, and the main East/West street ran along modern-day Leyden St. in downtown Plymouth. Since archaeological sites are often disturbed by construction from later periods, we used historic maps provided by Plimouth Plantation to find areas with the best potential for the preservation of 17th-century material.

The eastern perimeter of Burial Hill has two qualities which make it a good place to start looking. First, the modern landscape is a larger open area, making it a good location for a geophysical survey. Second, according to old maps, we know there were buildings running along School St. in the 19th and early 20th centuries and probably earlier. If these buildings were built on top of older deposits, they may have preserved 17th-century material for us to find.

Brian Damiata, the geophysicist on the team, analyzed data from the Ground Penetrating Radar (GPR) survey conducted in 2013 to help us determine where to place our excavation units. Our first priority is to not disturb any potentially unmarked graves on Burial Hill. Luckily, GPR can identify unmarked graves so that we can avoid them. The GPR survey also showed anomalies which appeared to be the foundations of 18th and 19th century buildings along school street a safe distance away from the graves on Burial Hill.

So far, the historical data and geophysical data have worked hand in hand to help us figure out where to dig next. Now that we have opened up a few excavation units, archaeological data can help us make even more informed decisions.

Changing Strategies at Deb Newman

As a general rule archaeologists have to be flexible, willing to rework their hypotheses and sampling strategies over the course of a project. Though we recovered nails, brick, and creamware from our 2 X 2 M units, which date our deposits to the correct time period, we aren’t satisfied that that particular area is the site of Deb Newman’s late 18th/early 19th c. home. To determine if the artifacts we found in our original excavation area were the result of artifacts washing down slope from a possible barn foundation higher up Keith Hill, we’ve begun digging shovel test pits every 10 M between the foundation and treeline. The test pits were based in part on a map created in ArcGIS by Doug Bolender of the Fiske Center showing statistically significant clusters of “A horizon”, the geographic strata where material culture related to Deb Newman would be located, from the 2010 and 2011 shovel test pits (pictured below).

While in another context the color change in the soil might suggest that these stones were used for drying fish or meat, the lack of artifacts point to the color resulting from excessive iron in the soil from the stones. The area also has the potential to be a riverbed, but we won’t know more until Dennis Piechota, the conservator at the Fiske Center who specialized in micromorphology, micro-excavation and elemental analysis of artifacts and the soil matrix, is able to examine them.

Front Page Boston Globe Story on Archaeological Excavations in Plymouth: The mystery of where Plymouth got its start

Boston Globe article about work in Plymouth

Boston Globe article about work in Plymouth

There is a wonderful page 1 story in the Boston Globe today about the work in Plymouth.  Dave Landon does a great job in the attached video explaining the work.  There are also a series of very nice photos that go with the story.  If you have trouble with the Globe site, you can see a printed version here.  The Author, David Filipov, has done a number of great stories.

EU7 3D views of the bricks

EU7We were out taking pictures of the bricks in Excavation Unit 7 on Burial Hill in Plymouth yesterday and Doug Bolender put together another 3D view.  This one is can be viewed on the web, and does not require downloading like the last one.   EU7 is where, according to the 1874 Beers map stood a school, probably the one that gave the street its name.  You can see the whole map at the Boston Public Library (Leventhal Map Center).

Ground Penetrating Radar and Excavation Unit 3

In this GPR Slice image, made by Brian Damiata, hard reflectors from the Ground Penetrating Radar (GPR) survey are shown in yellow and red.  In this GPR- slice, blue areas did not return any energy.   This slice is from about 90 cm below the ground surface.  The location of the hard reflectors (red and yellow) suggest that the stone wall excavated in EU3  probably continues to the southeast.   EU3 is the excavation with the overhead image superimposed.  If you look closely, you can see a row of stones in the east.  You can see more of EU3 in a previous blog post.  The red lines in the jpg are our best estimate as to the location of structures in the 1874 map, also described in a previous blog post.
