Figure 7.4. Plot of principal component scores of the elemental compositions of ceramic vessels from northcentral<br />

Pennsylvania.<br />

occurring zircon-rich igneous rock (e.g., quartz,<br />

feldspar, etc.) and sand inclusions in the paste. 1 Elam et<br />

al. (1992:95-96) argue that if a significant amount of zircon<br />

is present in the sand (as well as the igneous rock<br />

particles), the paste may exhibit a compositional profile<br />

that is enriched in Zr.<br />

The West Branch Group consists of four sherds with<br />

two (40 percent) from St. Anthony’s and two (40 percent)<br />

from Fisher Farm (Table 7.3, Figure 7.4). Clay<br />

sample 5, which is from north of the West Branch of the<br />

Susquehanna River, also clustered in this group. In this<br />

group, all of the sherds from the Fisher Farm and St.<br />

Anthony’s sites were assigned to Clemson Island<br />

types, having cordmarked exterior surfaces with nodes<br />

and/or punctates around the exterior rim and neck. All<br />

of the sherds had a crushed-quartz temper that measured<br />

between 1-2 mm in size. One sherd from St.<br />

Anthony’s is laminated in profile and one from Fisher<br />

Farm contains evidence of manufacture by coiling<br />

(Rieth 1997). St. Anthony’s, Fisher Farm, and clay sample<br />

5 are located in central Pennsylvania south of the<br />

West Branch of the Susquehanna River. This area is<br />

commonly regarded as the “heartland” of the Clemson<br />

Island tradition. Therefore, it is not surprising that the<br />

members of this group all exhibit attributes consistent<br />

with Clemson Island types.<br />

The Unknown group consists of nine sherds, four<br />

(44.4 percent) from Tioga Point Farm and five (55.6<br />

percent) from St. Anthony’s. Five (55.6 percent) were<br />

assigned to Clemson Island types and four (44.4 percent)<br />

to Owasco types. None of the five clay samples<br />

clustered in this group, making it difficult to determine<br />

where the vessels were manufactured. Although<br />

most of the sherds in this group are cordmarked and<br />

have a medium quartz and chert temper, one sherd<br />

from St. Anthony’s is shell tempered. Small open cavities<br />

were visible, suggesting that pieces of shell<br />

(and/or other organic materials) may have either disintegrated<br />

during firing (Rieth 1997) and/or leached<br />

out after breakage.<br />

The Unknown group represents a tightly clustered<br />

set of data points, which (at the 90 percent confidence<br />
