During the summer of 1969, avocational archaeologists from the Saginaw area conducted a test excavation at the Caster Site (20SA316) in Swan Creek Township, Saginaw County, Michigan. They staked out a 10’X30′ block divided into 5’X5′ excavation units and began their work. They recorded their findings on graph paper scaled 1 inch to the foot and supplemented their records with color movies documenting their progress at the site. According to a brief report published in the Saginaw Valley Archaeologist (Ray and Woodworth 1969:26), by September of that year they had recovered 12 projectile points, numerous ceramic sherds, a few chips and flakes, one celt, much fire-cracked rock, and numerous fire pits, post molds, and bone fragments. Some of the material excavated from this site eventually ended up at the Castle Museum. Unfortunately, maps, notes, photos, or other documentation did not accompany the artifacts and are now presumed lost.
The artifacts from this site now held in the Castle Museum Archaeological Repository include lithics and ceramics typologically consistent with Middle Woodland and Late Woodland occupations. At least nine grit-tempered ceramic sherds (seven after refits) appear to be from a single vessel, probably Middle Woodland in age.
The vessel is decorated with bands of oblique and horizontal dentate stamping on the smooth exterior rim and neck and additional dentate stamping on the interior lip/rim juncture. The lower rim also exhibits a row of exterior nodes/interior punctates within the band of dentate stamping. The body/shoulder of the vessel is cord-roughened below the band of horizontal dentate stamping on the neck. From the neck up, this vessel closely resembles the Middle Woodland ceramic type Tittabawassee Dentate Stamped as defined by Fischer (1972) at the nearby Schultz site. Below the neck is a different story. None of the Tittabawassee Dentate Stamped vessels described by Fischer at the Schultz site, or by Halsey (1976) at the (also nearby) Bussinger site, exhibit cord-roughened bodies. When cord-roughening is evident on Tittabawassee Dentate Stamped vessels it is generally well smoothed-over. That is not to say that cord-roughened surfaces are outside of the local Middle Woodland repertoire. Undecorated rim cordmarked (cord-roughened) vessels were present in nearly every stratigraphic level at the Schultz site, including Middle Woodland levels (Fischer 1972:185). Cord-roughened vessels decorated only with a row of nodes around the rim or neck were also present in Middle Woodland levels at both the Schultz and Bussinger sites. At Bussinger, Halsey (1976:193) defined a provisional type, Tittabawassee Cord-marked Noded, to describe such vessels.
Despite the unusual surface treatment, this vessel is probably best described as a variety of Tittabawassee Dentate Stamped. Like other vessels of this type is likely to date within the period of 100 B.C. to A.D. 400.
