Artifact of the Month – March 2021

This month’s artifact is a ceramic sherd. It is a piece from the base of a round, flat-bottomed ceramic vessel. The vessel was made out of clay with crushed mussel shell added as temper to prevent cracking while firing and to increase the vessel’s strength after firing. The sherd measures 52 mm (2 inches) wide, 63 mm (2.5 inches) long, and 6.7 mm (0.26 inches) thick and weighs 22 grams (0.78 ounces). What makes this sherd especially interesting is that it has an impression on the outside surface of a mat or basket it was sitting on while the vessel was being formed and the clay was still wet and malleable.

This sherd was found at the Heber Springs site (3CE68). At one time the Heber Springs site included a low, oval mound. In 1979, Arkansas Archeological Survey archeologist Robert Ray conducted some salvage work there after he was contacted by the site’s owner. The landowner informed Ray that there was a good possibility the mound would be destroyed, as he had plans to sell the soybean field where the site and mound were located for development. In addition to mapping the site, Ray and other Survey archeologists excavated a 30-meter-long trench and four small test units into the mound to study the techniques and timing of mound construction. This basket-impressed base sherd was excavated from a unit near the southern end of the mound at a depth of 28 to 38 cm below ground surface (or 130–140 cm below datum) in unit N12 E48 E1/2. A small Scallorn arrow point was also excavated from this level.
Basketry impressions on flat-bottomed vessels have been recorded elsewhere, mainly from mid-to-late Woodland period sites (Dellinger and Dickenson 1942; Horton 2010:405; Sabo et al. 1990:75). In Arkansas they have been found at the Wild Violet site (3LO226), 3LO183, the Poole site (3GA3), and the Crooked Creek site (3FR26), although these examples are on clay-tempered, rather than shell-tempered, sherds (Hoffman et al. 1977:53; Wood 1981:33). Shell-tempered flat-bottomed ceramics with basketry impressions on the base were reported from the Ira Spradley site (3NW101) and 3CE12 to mention just a few (McGimsey 1959:19; Sabo and Hilliard 2008). One such vessel from Ira Spradley yielded an AMS date of cal. A.D. 652–882 at 2 sigma [CALIB 7.0.4 on 1280 ± 60 B.P. (Beta-123306; d13C= -21.3%)] (Sabo and Hilliard 2008). AMS dates are currently being processed, but similar dates are anticipated for use of the Heber Springs site.

Organic material such as grasses and wood need special environmental conditions to be preserved. In the Ozarks, bluff shelters have provided a consistently dry environment and allowed for the preservation of seeds, wooden objects, bags, sandals, mats, and baskets (see Artifact of the Month for October 2019,  January 2018, and June 2018). Detailed studies of the perishable material from the Ozark bluff shelters at the University of Arkansas have yielded some incredible insights (Fritz 1986; Horton 2010; Scholtz 1975). Unfortunately, that type of preservation in artifacts made out of plants is very rare in the southeastern and midwestern United States, and unless the objects are carbonized (charred), they will not be represented in the archeological record. Sometimes, if we are lucky, we can learn about the types of fabric and basketry made by Native People by looking at impressions left on ceramic surfaces. In the case of this month’s artifact, we can observe that the people living at the Heber Springs site were making and using coiled baskets. Based on observed use-wear and their overall form, coiled baskets were likely made for food preparation activities like parching and cooking (Horton 2010:408). A more comprehensive study of ceramic sherds with basketry impressions and comparison to preserved basketry from bluff shelter sites in the future will lead to greater understanding of the technology, foodways, and relationships among Native People of Arkansas.

Artifact of the Month Series

A first principle of archeology is that the significance of artifacts depends upon documented information about the context of their discovery. At what site was the artifact found? Can we figure out the age of the artifact? Where was it found in relation to site features (houses, trash deposits, activity areas, etc.) and the distribution of other artifacts? Only with knowledge of those facts can we assess further information about the manufacture and use of artifacts, and their role in other spheres of activity such as social organization, trade and exchange, and religious practice.
In this series, we feature select artifacts that are extraordinary both for the context of their discovery and for their unique qualities that contribute exceptionally important information about Arkansas culture and history. New artifacts will be added monthly. Find the list of artifacts here.
