Jefferson County Revisited


Back on the alphabetical trail this week through Pennsylvania Archaeology and we arrive at the letter “J”. With options like jasper and Jack’s Reef points discussed in earlier posts, “J” becomes a bit more difficult to find a match for.  Revisiting Jefferson County might not be the most creative solution but it does provide an opportunity to look at a recent cultural resources management project or CRM. Cultural Resource Management is a review process that aids in the protection and management of our cultural heritage under state and federal guidelines. This may include archaeological resources, but also addresses historic buildings. Cultural resources are finite and non-renewable resources that once destroyed cannot be returned to their original state.

Jefferson County is home to Summerville, a small village situated along the northern and southern banks of Redbank Creek, a meandering tributary that forms the border between neighboring Clarion and Armstrong Counties and eventually meets the Allegheny River further west.

As seen in the historic aerial photo above, Summerville’s only bridge linking the northern and southern sections of town spans the creek at a perpendicular angle. PennDoT proposes to replace the bridge, “on a new alignment skewed across the creek . . . in order to improve the horizontal and vertical geometry and eliminate two 90 degree turns to the north of the existing bridge.”(Raber, Heberling and Vento 2012)

 Due to receiving federal funds, PennDoT undertakings are required, among other things, to make a good faith effort in identifying cultural resources, evaluating their significance, and if necessary, mitigate any adverse effects their projects may have on important archaeological sites. In 2011, Heberling Associates, Inc. was contracted by PennDoT to conduct a phase I archaeological survey of the bridge replacement project’s area of potential effect, or APE.

 Referencing the Bureau for Historic Preservation’s Cultural Resource Geographic Information System (CRGIS), no fewer than eight previously recorded archaeological sites have been identified in the vicinity of Summerville, suggesting a high probability of a site within the project area. Directly abutting the existing bridge a steep slope, recent erosional activity of Redbank Creek and modern demolition work eliminated the need for subsurface testing in three of the four quadrants of the project area. However, in the southeast quad geomorphological analysis indicated the potential for intact cultural remains in Holocene age soils.

Four 1 x 1 meter test units in the southeast quad of the project area were hand excavated to sterile soils. Thirteen pieces of Onondaga and Upper Mercer chert debitage were recovered from A horizon (topsoil) contexts across each of the four units, one of which exhibits slight utilization wear on opposite margins. No other prehistoric tools were found and none of the lithics could be assigned to a particular time period.

 Several dozen historic artifacts were also recovered including earthenware and stoneware ceramics, vessel glass, a kaolin pipe stem fragment, and miscellaneous architectural materials. Two heavily corroded U.S. one cent pieces were found in stratum 2 of Unit 3. Although the obverse of both are so worn the dates are obliterated, enough of the reverse remains to identify one as a “wheat” penny, produced from 1909-1958, and the other as an “Indian Head” penny, minted from 1858-1909 (Yeoman 2001).

The cultural review process requires resources to meet certain criteria http://www.nps.gov/nr/publications/bulletins/nrb15/nrb15_2.htm  in order to meet eligibility standards.  The light density and non-diagnostic nature of the prehistoric finds, and the historic artifacts’ lack of spacial integrity or association to important people or events, renders the Summerville Bridge site (36Je178) not eligible to the National Register of Historic Places, and no additional archaeological testing has been recommended prior to the construction of the new bridge.

While not an exceptional archaeological site yielding new, interesting finds that will turn Pennsylvania Archaeology on its head, the Summerville bridge replacement project serves as an example of the numerous transportation projects throughout the state where PennDoT has (after the artifacts and associated documentation have been submitted to the State Museum of Pennsylvania, of course!) done its due diligence in helping to preserve the past for the future. These cultural resource management projects have provided archaeologists with an opportunity to look at archaeological resources all across the Commonwealth. Well documented and carefully prepared reports have provided us with a much improved picture of our archaeological heritage thanks to these investigations.

Jefferson County




TWIPA would like to thank Kenneth Burkett, executive director of the Jefferson County Historical Center, for guest blogging this week. We continue the county by county archaeological journey with Jefferson County. 

Situated in the uplands of the Appalachian Plateau physiographic region this area consists of rolling hills and moderately steep sided valleys covered in regrowth hardwood forest.  

Transecting the county are three major westward flowing waterways with the Clarion comprising the northern boundary, the Redbank Creek in the center and the Mahoning Creek near the southern border.  These waterways were important transportation routes for Native Americans travelling between the Susquehanna and Allegheny River basins requiring only short portages over the divide between their upper tributaries and the West Branch.  The presence of these prehistoric inter-regional travelers is frequently found on streamside campsites in the form of artifacts made from non-local lithics such as jasper, rhyolite, quartzite and argillite along with an occasional steatite bowl fragment from eastern Pennsylvania. From the west, Upper Mercer, Coshocton and Flint Ridge lithics originated in central Ohio.

As this area is unglaciated, the primary sources of chert are within the Pleistocene gravels of the Allegheny river and a poorer grade of local Vanport siliceous shale also referred to by archaeologists as Jefferson County chert (Burkett 2001).  This black and tan chert outcrops on hillsides in the central part of the county where several prehistoric quarry sites are known. Many more probably existed prior to their destruction by 20th century strip mining.  Often found at these locations are the stone digging picks used to expose the chert veins. Hammerstones and anvil stones are evidence that the raw material was tested for quality and the initial shaping of the tools began at the quarry. This process also served to reduce the weight of the tool blanks prior to transporting them to the habitation sites. Many of the rockshelters along the Redbank and Mahoning creeks contain enormous quantities of chert chips produced while refining or finishing these tool blanks.
Jefferson County Chert Artifacts

Formal archaeological investigations of prehistoric sites have rarely been conducted in this county. The only reported excavations are the Bunny Rock Rockshelter (36Je48), the Ridge Rockshelter (36Je49) and the Davis Rockshelter (36Je50) excavated in the Redbank drainage between Brookville and Summerville by Ken Burkett (nd.). In addition, the Dutch Hill Rockshelter (36Je132) near Belltown overlooking the Clarion River was excavated by Andrew Myers (2001).

Jefferson County has an extensive 19th century logging history and there are many remnants of mills, raceways, bracket dams and railways found throughout the county in and along the streams and tributaries.  Annually each summer since 2005, Brian Fritz and Amanda Valko have been working at Clear Creek State Park to present a public archaeology program where volunteers help excavate, catalog artifacts and document a blacksmith’s shop that was part of the circa 1870’s Frazier Sawmill complex.

We hope you have enjoyed this short overview of Jefferson County and that this will inspire an interest in recording and preserving the archaeological sites in your community. For more information on the history of Jefferson County visit the web site at www.jchonline.org. These resources are Pennsylvania’s heritage and for all of us it is our window into the past.  Help us to protect and preserve these archaeological resources which are crucial to our understanding of the past. We encourage every citizen to take an active role in preserving our archaeological heritage and ask that you respect these sites and Preserve our Past for the Future.

The 98th Annual Pennsylvania Farm Show opens on Saturday, January 7th, 2013. This year’s exhibit theme is the Archaeology of the French and Indian War (1756-1763). We will be showcasing the State Museum’s excavations at Fort Hunter as well as excavations at Fort LeBoeuf, Fort Augusta, and Fort Loudoun. A brochure detailing the archaeology of this time period will also be available.  Our exhibit wouldn’t be complete without the 20’ dugout canoe which is always an eye catching attraction. French and Indian War period re-enactors will be present to answer questions and tell stories. Also, this year the Bureau for Historic Preservation’s exhibit booth will be located directly across the aisle from our own booth, providing a united display for the PHMC.
