The Holtz Site is located on the bank of the Intermediate River on what once was as island, surrounded by low, swampy ground. Five different features were discovered at the site. These were:[4]
A small hearth measuring about 1.4 by 1.5 feet.
A concentration of potsherds.
A modern fire pit.
Materials associated with hearth activities, but no the hearth itself.
A second concentration of pottery.
The sherds belonged to at least 11 distinct pottery vessels, of which six were complete enough for identification of features. Several projectile points were also recovered from the site.[4]
History
The materials present at the site indicate that it was occupied late in the Middle Woodland period.[4]
The site was excavated in 1967 by researchers from Michigan State University.[5] Artifacts found on the site indicate it was a Middle Woodland period encampment, dating to around AD 200-400.[6] It was likely inhabited for a short time by people from southern Michigan who traveled north for a season.
