Cemeteries - Stories of the Past

When was the last time you were at a cemetery? For many it was likely to bury a loved one- a family member or a dear friend. It’s likely that you didn’t look around at the other cemetery markers, unless they were family members, and think about the individuals who are represented by the marker.  Most of us wouldn’t consider a cemetery to be a garden or park, or that it may have been arranged based on political or social status. We tend to think of cemeteries as a final resting place for the dead, a place we might visit to pay respect and reflect upon a memory.

Preservation movements across the United States have begun to recognize the significant resources preserved in cemeteries; these are not simply the source of genealogical records, but they also represent important cultural sites on the regional landscape and their significance varies for different ethnic groups.  Unfortunately, they are threatened by development and neglect that is eradicating them from the landscape.  In rural areas family cemeteries were frequently located near a few trees or some other marker on the landscape that may no longer exist.  Recording the locations and data associated with cemeteries has become a preservation initiative for many groups at the local, state, and national level.

In Pennsylvania, the State Historic Preservation Office (SHPO) has created a process in PA-SHARE for recording cemeteries in a Cultural Resources Geographic Information System (CRGIS).  The help page for this site will guide you in completing the required information. This office has also been involved in efforts to improve guidance for state agencies surrounding the treatment of cemeteries. This work was initially inspired by the discovery in 2016 of a cemetery on Arch Street in Philadelphia during a construction project.  The site was the location of burial grounds for the First Baptist Church of Philadelphia. The remains of more than 400 individuals dating to between 1700 and 1860 were recovered during an emergency salvage archaeology project conducted by volunteer archaeologists in the area. Unfortunately, this is just one example of cemeteries being lost in the historic record, only to be discovered “at the last minute” during a construction project.  

Protection of Native American cemeteries gained momentum in 1990 with the passage of the Native American Graves Protection and Repatriation Act (NAGPRA). Unfortunately, many grave sites were looted and destroyed before this Act went into effect, and some are still threatened by this criminal activity. 

Attention has grown within the African American community for finding, recording, and preserving their ancestral cemeteries. The Pennsylvania Hallowed Grounds project is drawing attention to preservation of cemeteries and is specifically focused on honoring Pennsylvania’s United States Colored Troops (USCT), veterans of the American Civil War who fought in African American regiments. The Lincoln Cemetery in Cumberland County was recently placed on the county register of Historic Places. Twelve African American veterans of the U.S. Civil War, members of the U.S. Colored Troops, are interred here along with the remains of other members of the African American community dating back as early as 1862.  This cemetery was recognized as important to the community by members of the Vietnam Veterans of Mechanicsburg who took on the task of cleaning and restoring the overgrown cemetery. This is an excellent example of the local community recognizing the contributions and sacrifices of these soldiers and honoring their final resting place. 

The difficulty in tracing these individuals and African American cemeteries in general can be attributed to several factors.  Enslaved peoples were often buried in unmarked graves in remote areas, family members may have been sold, or for some, escaped via the underground railroad. Graves were sometimes marked with wooden staffs or in coastal areas, piles of shells delineated the burial. Often these types of markers were lost or decayed, leaving no trace of the grave itself and no record of the individual buried there.  After the Civil War, families often moved out of the area and future generations never returned. Cemeteries in more urban settings were equally as threatened by development and racist treatment of African American burial grounds. Segregated cemeteries didn’t receive the same treatment and respect as the more affluent cemeteries and were often the first sold by local governments. Historic records often indicate that graves were moved but have proven to be inaccurate at best. Oral histories preserved in the local communities have often been the best resource for preserving these burial grounds.

Archaeologists from the Pennsylvania Historical and Museum Commission recently met with the Friends of the Lebanon Cemetery in York, York County to discuss efforts for preserving this African American cemetery.  The cemetery was begun in 1872 but contains remains of individuals originally buried in other locations and moved to this site. Some graves were marked, but many were not. Community members have researched the family members who are buried here and have worked diligently at cleaning up the cemetery and recording data on head stones. Soil erosion on a steep hillside has led to damaged headstones and misplaced or buried markers.  The group was seeking assistance in locating unmarked graves and guidance for best practices in sharing their information. Staff from the SHPO’s office, The State Museum of Pennsylvania, and West Chester University toured the area and considered options for this group. West Chester University archaeologist Dr. Heather Wholey, and students suggested creating a detailed map of the graves along with the gravestone information as an initial step in this project.  Newer technology for identifying graves including the use of drones and remote sensing surveys were also discussed as possible options.  GroundPenetrating Radar (GPR) is a method employed by archaeologists to identify disturbances and anomalies in the soil.  It is a non-destructive method for mapping data into a GIS system which enables the identification of potential burials and provides a plan or map of the cemetery.

Recognizing cemeteries as cultural landscapes and the data that can be gleaned from them is an important effort in understanding our past.  Identifying the individuals, the communities and ultimately the cultures represented in each of these cemeteries is gaining recognition as a resource for archaeologists, historians, genealogists, and preservationists.  Cemeteries associated with communities that sprang up along the Underground Railroad show patterns of movement and cultural adaptation. Understanding the past of the underrepresented allows us to evaluate deeper social issues of injustice and racism. 

African American cemeteries have always represented significant places in African American society, but conditions did not allow these cemeteries to achieve the same prominent monuments as white cemeteries. They are now being recognized as significant monuments that serve to memorialize African American individuals and their contributions that are not recognized elsewhere in white history books.

Preserving cemetery records is vital for groups researching their community and individuals searching for their ancestors. Awareness of the significance of these documents is fundamental to this preservation effort. Archival institutions such as the Pennsylvania State Archives have the tools and technology necessary to preserve records for future generations.  Recent federal legislation was created to record and preserve African American cemeteries; this initiative will also help to unite resources for local community-led programs.

On October 30th, 2021, The State Museum of Pennsylvania will host the annual Workshops in Archaeology program as a virtual program. This year’s focus on African American stories revealed through archaeology and cemetery projects across the Commonwealth and mid-Atlantic will expand on this topic. Presentations by archaeologists and historians promise to raise awareness of the contributions made to Pennsylvania and the nation.

The Most Common Artifact Recovered from Precontact Archaeological Sites - Let’s Get Flakey

A basic guide to stone or lithic flake terminology.

        What is the most common artifact recovered from Precontact archaeological sites? Not arrowheads or spear points or pottery sherds that get all of the attention, but flakes – the  unmodified and unused by-product of chipped stone tool production. Also known as chips, detritus, spawls, shatter or over the past twenty years, most commonly labeled as debitage, these artifacts are ubiquitous at Precontact sites. They outnumber the tools by at least 100 to 1. Flakes are usually the first artifacts that are found during site surveys, and sometimes the only evidence of a Precontact occupation but they are frequently overlooked during analysis and usually lumped together as a single artifact type. Flakes are not pretty; they usually appear as relatively small slivers of rock and even the larger pieces are not readily recognizable as artifacts to the untrained eye. For a long period in archaeological research, flakes were not thought to be very useful in interpretating past cultural behavior. For example, the early collections in The State Museum of Pennsylvania from the 1920s and 1930s contain more projectile points, pottery and bone objects than flakes. Up until the 1970s, some professional archaeologists did not bother to curate flakes during otherwise systematically excavated site investigations but tossed them in the trash at the end of the day. “Flakes tell us Native Americans made stone tools – so what!”

       Based on flint knapping experiments beginning in the 1960s, (Crabtree 1972) and becoming common in the 1980s (Callahan 1979), the interest in debitage and the potential contributions to the interpretation of past cultural behavior became more common. Now, the analysis of debitage is usually a regular part of archaeological survey and site reports. These artifacts tell a great deal about the activities at sites and the tools that were being made and as John Whittaker (1994:21) observes, the occupants of a site were “so inconsiderate as to take the useful tools away” so in many cases the flakes are the only evidence to interpret the past.

The literature is now voluminous, and the following will serve as an introductory or basic guide to the terminology used in describing flakes and the analysis of debitage. All flakes are not the same, but they share certain characteristics. Let’s begin with some terminology. The block of stone to be hit is called the core (to the left in the above illustration) and the pieces that fly off are the flakes (to right). Basically, when a hammerstone hits the edge of a core, the force of the hammer is transmitted into the core; energy is most pronounced at the point of impact and gradually dissipates outwardly to the distal end of the flake. The interior surface of the flake, facing the core is the ventral surface. The exterior side of the flake facing out is called the dorsal surface. At or just below the point of percussion, also known as the striking platform, there is a swelling on the ventral surface known as the bulb of percussion. Further down the ventral surface of the flake are ripple marks. On the dorsal surface there are flake scars where previous flakes were removed from the core. These are characteristics found on stone that was broken for stone tool production; they are not commonly found on stone that broke through natural processes.

In a sense, making stone tools is comparable to a wood carver whittling wood. It is a subtractive process, beginning with an amorphous shaped natural block of stone and ending with a finished tool. The process of making stone tools is called knapping or more commonly, flint knapping. Knappers use a stone where it is possible to predict the manner in which it breaks. Just as important, knappers must be able to control the break so that tools can be shaped. The characteristics of the lithic material typically used to make chipped stone tools, also known as “toolstone”, is that they are relatively hard, brittle, plastic and homogeneous, containing few impurities. This type of stone breaks with a conchoidal fracture (cone shaped) similar to a bee bee shot through a windowpane. Flakes usually exhibit a subtle curve in one or more directions. In Pennsylvania the most common lithic materials used in the production of chipped stone tools are chert, jasper, quartz, quartzite, argillite and metarhyolite.

         Knapping usually requires three different types of tools to break the stone - two types of hammers and a pointed piece of antler. An abrading stone is used to prepare and shape the striking platform so that flakes can be more easily and precisely removed. The hard hammer is for breaking up the blocks of stone from the quarry into manageable blanks. These may range in size from a baseball to a bowling ball weighing ten pounds or more. A soft hammer or baton is usually made from antler (moose or elk) or hard wood (ash or hickory) measuring less than a foot in length. These are for thinning the blanks into nearly finished pieces. The final sharpening and shaping is usually performed with a pressure flaker, commonly made from antler. The point of the antler is placed on the edge of the tool and small flakes are pressed off rather than struck. This is the most precise technique of flake removal.

The key to the analysis of debitage is that the hammerstone, the baton and the pressure flaker all produce different shapes of flakes and therefore the different technological activities can generally be identified. Hammerstone flakes are relatively thick and especially the bulb of percussion is pronounced. Hammerstone flakes are generally produced during the initial stages of tool production, so they have fewer flake scars on their dorsal surface and even less evidence of previous flaking and grinding on the striking platform. Baton flakes are relatively thin, and the bulb of percussion is diffused as the percussion blow spreads out evenly below the striking platform. There are usually many flake scars on the dorsal surface coming from multiple  directions and the striking platform shows evidence of grinding and pressure flaking so the flake can be removed more precisely. In addition, when working a biface (a biface is worked on both flat surfaces of the stone), such as a knife or spear points, baton flakes frequently exhibit a distinctive lip on the striking platform. This is a remanent product of the tool edge that offers evidence of the thickness and size of the tool. Pressure flakes are smaller, usually less than ¾ of an inch in length and thin, often with parallel sides and the striking platform is usually more heavily ground for better attachment.

Complicating the analysis of debitage is that less than half of the flakes are normally complete; most are broken in some fashion and therefore the striking platform or bulb of percussion is missing, something not very useful in the analysis of debitage. In addition, these characteristics or attributes are somewhat subjective, and identifying these traits is very time consuming. However, when applied to large collections, the attribute analysis of debitage can be useful in distinguishing different kinds of knapping activities at a site. Identifying the location of early stone tool production, the location of actual tool production areas, the final sharpening and shaping of tools, and the resharpening of tools can be valuable information in the interpretation of activities at a site.

There are other types of flakes that define more specific technological activities such as blade flakes, biface thinning flakes, overshot flakes, bipolar flakes, and platform rejuvenation flakes and these can be the topic of future blogs.  

The foregoing methodology is based on the identification of specific attributes on flakes. Especially, as large state and federal projects in compliance with the National Historic Preservation Act became more common, archaeologists became more concerned with the accuracy of the attribute analysis but also the time involved in flake analysis. In response, a variety of alternative methods have been developed. Generally, these fall under the term aggregate analysis and involve sorting flakes by size using a series of graduated sieves (screens). Needless to say, these other methods are complicated and there is not sufficient space to describe them all here. Spoiler alert, it is generally agreed that the best results are achieved using a combination of attribute analysis and aggregate analysis (Hall and Larson 2004).  

As noted by Jeffery Rasic, considering the high frequency of flakes at sites, they are “one of the primary sources of information about human behavior … being able to reconstruction technological behaviors related to production, use, transport, and maintenance of stone tools … these data and interpretations, in turn can shed light on questions of broader anthropological concern such as the ways people organize their work, subsistence activities, travels, and social and political behavior” (Rasic 2004:114). Many studies have demonstrated that debitage at sites changes during different time periods suggesting that debitage reflects the basic characteristics of the cultural adaptation (Parry 1994).

 We hope you have enjoyed this brief overview of debitage terminology and more carefully examine the next flake you find realizing that it has an interesting story to tell. Please visit our gallery at The State Museum of Pennsylvania to see examples of stone tool production by the Indigenous peoples who developed and perfected this technology.  We also invite you to visit our on-line collections.
