Adena Robins Point

This triangular stemmed point exhibits a distinctive morphology, characterized by a medium to large size and a cross-sectional profile that ranges from flattened to elliptical. The blade itself is notably broad, with a predominantly excurvate shape that reaches its maximum width just above the pronounced shoulders. These shoulders are often slightly barbed, although they can also be oriented horizontally. The stem is proportionally slender, with a square shape and rounded corners at the base, which is typically longer than it is wide. The basal edge is generally straight, but may occasionally be convex, and is notable for the absence of grinding in the basal or hafting region. The point's manufacture involves an initial stage of random percussion flaking, supplemented by pressure flaking to refine and retouch the blade, resulting in a characteristic random flaking pattern.

The dimensions of these arrowheads are characterized by the following measurements: they typically range in length from 50 to 150 mm, with a mean length of 70 to 80 mm. The stem, a crucial component, measures between 15 to 30 mm in length, averaging 21 mm. In terms of width, the blade spans 23 to 55 mm, with an average width of 35 to 40 mm. The stem width ranges from 18 to 27 mm, averaging 24 mm. Lastly, the thickness of these arrowheads varies from 7 to 15 mm, with an average thickness of 9 mm.

These artifacts are located within the Ohio River Valley region. The typical dispersion of the Adena points is highlighted in red (see Additional Comments). The yellow area represents the sphere of influence and exchange network of the Mound Builders, encompassing the Adena, Hopewell, and Mississippian Cultures.

The Adena point, a distinctive arrowhead style, is predominantly associated with the Adena Culture, which flourished in the Ohio River Valley. Notably, similar points have been discovered within the broader Mound Builder Distribution, exhibiting comparable characteristics to the Adena point. Examples of these analogous points include the Waubesa point, linked to the Hopewell culture, as well as the Dickson, Mason, and Florence points, which are attributed to the Red Ocher Culture. When encountering Adena-style points outside the Adena Cultural area, it is essential to assess the possibility that they may represent similar, yet distinct, types.

The temporal context of these points is significant, with their usage spanning the late Archaic period to the early and middle Woodland period, as noted by Justice in 1987. Interestingly, early Adena points appear to have originated in the Tennessee River Valley, from which they disseminated during the early Woodland period, according to Kneberg's 1956 research. However, the Adena culture itself is believed to have originated and been centered in the Ohio River Valley. The evolutionary trajectory of the Adena point is thought to have commenced with the Cresap point, from which various adaptations and modifications emerged over time.

A closer examination of the Adena point's development and distribution reveals a complex and dynamic process, reflecting the cultural exchange and technological innovation that characterized the region during this period. The presence of similar points across different cultural contexts highlights the need for careful evaluation and consideration of the historical and archaeological context in which these artifacts are found. By examining the Adena point within its broader cultural and temporal framework, researchers can gain a deeper understanding of the technological, social, and economic factors that shaped the lives of Native American communities in the region.
