The Early Archaic period in
Pennsylvania corresponds with the end of the Younger Dryas climatic episode and
the beginning of the Holocene episode or the modern era at about 11,700 calendar
years ago. This is a very interesting time because it witnessed the most
significant environmental change of the past 40,000 years, although some argue
that the current episode of global warming will turn out to be even more
significant. Additionally, we see radical
changes in projectile points from the unique fluted points of the Paleoindian
period to the more common notched points of the Archaic period. During the
Younger Dryas, fluted points in the Northeast evolve from Clovis into points
with longer flutes and a fishtail shape eventually leading to a decreased emphasis
on fluting and finally to leaf shaped points with no fluting. Rather quickly, around
11,700 calendar years before present (BP), notched projectile points such as Thebes,
Charleston, Palmer, and Kirk appear.
Environmentally, at 11,700 calendar years
ago, this is a transition between the cold, harsh conditions of the Pleistocene
to the warming of the Holocene. The temperatures rose rapidly to modern
conditions, but it required approximately 1000 years for the open spruce pine
forest of the ice age to evolve into the oak and pine forest of the early Holocene
and 5000 more years to become the oak-hickory and hemlock forest of the later
Holocene. For Paleoindians, the long winters and coniferous forest did not
provide many plant food and probably 60% of their diet came from hunting small
game, deer, bear, elk, caribou in northern Pennsylvania and fishing. The closed
spruce pine forest of this transitioning period between 11,700 and 10,200
calendar years BP also did not provide many plant foods, although the winters
were shorter and oak trees, with their supply of acorns were increasingly
available for both human and animal consumption.
The drastic change in projectile
points has always perplexed archaeologists. The change from lanceolate forms to
notched forms suggests radical changes in the way they were hafted to the
shaft. Lanceolate points are found all over the world, but only in the Americas
are they fluted. The mechanism for hafting fluted points is generally
understood, but why the need for fluting is a mystery. Some archaeologists
believe that the change in spearpoint shape was related to hunting with an
atlatl in the dense coniferous forest of the Early Archaic period. However, others
argue it is more difficult to throw with an atlatl in a forest, so the jury is
still out on this issue. Hardaway and Hardaway-Dalton points are basially
thinned and notched and considered by some to represent a transition between
fluted points and Early Archaic notched points but these are very rare in
Pennsylvania.
Whatever, the reasons, the most
common Early Archaic projectile point types found in Pennsylvania are: Palmer
and Kirk, corner notched types; less common are Kirk side notched and
Charleston corner notched types and lastly, the Thebes type has only been recovered
from a few sites. Generally, they all have a ground base and are serrated. Like
fluted points, most are made from chert or jasper, although metarhyolite and
quartzite was also used.
Thebes Points (Justice 1987)

Again, based on stratigraphic
associations, the Charleston corner notched type occurs with the Thebes type
and below Kirk and Palmer types (Justice 1987). These are relatively broad
points compared to other types of this era. The blade is also frequently
asymmetrical again suggesting they were used as knives or scrapers. Two
Charleston points were dated to 11,408+750 at the St. Albans site in
West Virginia (Broyles 1971).
The Palmer corner notched type is a relatively
small point with a straight base and frequently with more pronounced serrations
(Coe 1964). The shape of the blade has been compared to a “Christmas tree”.
They have not been well dated in Pennsylvania, but at the Thunderbird site in
the Shenandoah Valley of Virginia, they were dated to 11,468+566 calendar
years before present (Verrey 1986). At the Richmond Hill site in New York, three
Palmer points associated with a hearth were dated to 10,595+180 calendar
years before present (Justice 1987).

The Kirk corner notched type has a large,
generally triangular blade with a straight or sometimes convex base. Compared
to the Charleston type, the blade is less frequently asymmetrical. In addition,
these points are thinned by flakes that extended across the mid-line of the
point (Justice 1987). This type has been dated at several sites in Pennsylvania
to between 10,730+412 and 10,209+30 calendar years BP (Carr 1992).
Kirk side notched points are sometimes found above corner notched types in
stratified alluvial settings and usually below bifurcate base points, but there
are few if any dates on this type (Carr 1992). Kirk stemmed points have been
found in the same levels as bifurcate points at several sites (Daniel 2011).
The Early Archaic sequence presented above
– Thebes, Charleston, Palmer, and finally Kirk seems reasonable based on
stratigraphic associations. Daniel (2011) published a re-analysis of Coe’s (1964)
work that essentially supports the above chronological sequence for these
types. However, the radiocarbon dates do not support a sequence of dates for
these types, but rather suggest several types were contemporary and were being
used at the same time. Part of the problem is there are a limited number of
dates and most of them cover a wide range of time. Or these types, in fact,
overlap in time and were used throughout this period by different bands or had
different functions. Obviously, it is necessary for archaeologists to obtain
more dates from stratified contexts and use the most refined dating system
available (ie AMS dates) to further our understanding of this time period.
In conclusion, it is clear that the
Early Archaic projectile point types were part of the adaptive strategy for
exploiting the post-Pleistocene environment that was transitioning to a more diverse
deciduous forest at about 10,200 calendar years BP. Although there is a slight
overlap with Kirk points, bifurcate base points were the main lithic projectile
point used to exploit this initial phase of the evolution of the deciduous
forest in the Middle Atlantic region.
We hope you’ve been inspired during
these cold days of winter to consider the harsh environments that prehistoric
peoples encountered and their survival techniques. A better appreciation and
understanding of our past, helps us to consider change and adaptation for the
future. If you’d like to learn more
