This Week In Pennsylvania Archaeology takes us to Schuylkill
County located in the mountainous region of east-central Pennsylvania.
Schuylkill County was established in 1811 from lands claimed by the bordering
counties of Berks, Northampton and Northumberland. It was named after the
Schuylkill River. This is the major drainage through the county and it
eventually flows into the Delaware River at Philadelphia. The county is also
drained by the Swatara and Mahanoy creeks that flow southwestward into the
Susquehanna drainage.
Schuylkill County falls within the “Anthracite Uplands” and
the “Blue Mountain” Sections of the Ridge and Valley Province. The physical
landforms are characterized by hilly uplands and steep mountains ridges with
narrow to broad valleys typical to the general configuration of the Ridge and
Valley Province in east-central Pennsylvania
Geologically, Schuylkill County
is made up of coal and shale deposits that and Pennsylvanian and Devonian in
age (400 – 300 mya). These are the product of lush bogs and swamps that
eventually transformed into the anthracite coal beds of today. Some of the most
magnificent plant fossils in the Commonwealth have been found here. The ridge
tops all around the County are capped with a quartz pebble sandstone called
Pottsville conglomerate, named after the town of Pottsville, Schuylkill County.
During the earliest stages of the Pleistocene Period the
northeastern edge of Schuylkill County experienced
some level of glacial activity. At Tamaqua and other locations along and
bordering the Schuylkill River, till deposits of Pre-Illinoian age (greater
than 770,000 years) consisting of clayey to silty till and rounded cobbles have
been mapped by the Pennsylvania Geologic Survey. These ancient soil and gravel
deposits form a 10-30 mile wide band that extends from Lycoming County to the
Pennsylvania New Jersey border in Northampton County on the Delaware.
Tulpehocken Path Marker
Two Indian paths ran through Schuylkill County, the Nanticoke
and Tulpehocken. During the 18th century, and likely before and
after that time, these paths were direct inter-montane routes connecting other
paths to and from the Susquehanna and Delaware river valleys (Wallace 1971).
There were no major Indian towns established along these routes but stopover
camps or “sleeping places” would have been common and used at certain times by
Native Americans and Colonials, alike.

A review of the Pennsylvania Archaeological Site Survey
(P.A.S.S.) records identify 85 prehistoric and historic period sites in
Schuylkill County. The majority of these sites are attributed to eight
prehistoric periods with the Late Archaic accounting for most. Transitional
Period sites are followed by Middle Archaic Period sites. Paleoindian, Early
Archaic, Early Woodland and Late Woodland sites are few in number and with the
exception of Paleoindian and Late Woodland sites where projectile point types
are very diagnostic, some of these sites may be misrepresented by the generic
stemmed and notched styles common to some of these cultural periods. This
typology dilemma becomes a real problem that archaeologists encounter when
attempting to identify site occupations where radiocarbon dating and other
forms of cross dating artifacts cannot be accomplished. The prehistoric use of
quartzite, and jasper and chert reflect the availability of such lithic sources
in and surrounding Schuylkill County. The Hardyston Formation in the adjacent
Reading Prong Section southeast of the county, in particular, is the principal
source for quartzite and jasper.
Reported Historic Period sites are largely 19th
century in age and include farmsteads, industrial and transportation related
sites. Most of these sites were registered with PASS in the course of
conducting cultural resource surveys for roads and bridges.
The PASS files list site occupations as more-or-less evenly
divided between the uplands and valley floor settings. This statistic is likely
biased since there is more farming activity going on in the lowlands and hence
it is generally in those areas where on-ground surface surveys can be
undertaken.
At the onset of the French and Indian War, a string of log
forts was established along the south slope of Blue Mountain (Hunter 1960).
These forts was essentially the first line of defense against marauding Indians
sympathetic to the French cause in western Pennsylvania from 1754-1763. Some of
these were re- supplied and garrisoned during Pontiac’s short lived rebellion
in 1763. Two of the forts forming the line of defense in Schuylkill County were
forts Franklin and Lebanon, the latter renamed Fort William in 1757. As with
many of the log forts of the day neither was of substantial design or
construction.
Fort Lebanon Marker
Fort William referred to by Ben Franklin as “Fort Lebanon in
the Forks of the Schuylkill” (Hunter 1960) consisted of a barracks and
storehouse and two structures to harbor local settlers in dreaded times of
siege. All of this was protected by a 100 foot square log fort. History places
the fort near Auburn, a small rural community in southeastern Schuylkill County.
The other fort, Fort Franklin was built near present day Snyders, a town in eastern Schuylkill County. It was
the smallest fort of the line of defense on the north side of Blue Mountain.
Measuring only forty feet on a side, the log fort had two opposing bastions
that also served as dual defensive facilities. A third structure is thought to
have occupied the main courtyard.
Fort Franklin Marker
In 1984, through the generous cooperation of Mrs. Curtis
Bailey, Stephen Warfel from the State Museum and a staff of over 100 volunteers
from the local area undertook a ten day systematic survey and test excavation
project to identify the remains of Fort Franklin. Over the course of that
period a preselected area of the property measuring 200 feet by 300 feet was
investigated. In spite of not finding the fort nor any artifacts relating to
the fort the exercise provided participants with the opportunity to learn proper
methods and field techniques that are used by professionals to find and
excavate archaeological sites. The following year Barbara Lu, a student at Franklin
and Marshall College, conducted a magnetometry survey of the area.

The Bailey
property was again tested along with the adjacent Stahler property. This state
of the art methodology discriminates between low and high magnetic responses.
This methodology serves two practical purposes: 1) it allows for a large area
to be surveyed in a smaller period of time and 2) it is a nondestructive
procedure. What it finds, it records on the computer screen as a configured
archaeo-magnetic signature or the shape of the anomaly that it scans, such as
the wall trench of the fort. Identified
anomalies are then targeted and investigated at a later date to confirm the
magnetometry data. Although some anomalies were identified in the ground, none
were deemed of the sort that potentially marked the location of the fort site
or any of its expected features i.e. water well, interior buildings, bastions
etc.
outcrop where the Schuylkill County petroglyph was discovered
Over the years many fascinating discoveries have been made
in Schuylkill County. Nearly a half century ago, Francis Burke, a local amateur
archaeologist from Mar Lin, Pennsylvania discovered a rock carving or
petroglyph. His discovery, made on the
surface of a sandstone outcrop, was a human face carved in base relief. Mr.
Burke wanting to preserve the petroglyph contacted staff archaeologists at the
State Museum who moved the carving to Harrisburg where it now safely resides in
a climate controlled environment where it can be enjoyed by everyone.

Schuylkill County archaeology. Please join us next week when TWIPA will be
featuring Snyder County, Pennsylvania.
