Over the past two weeks, the Castle Museum archaeology team has spent several days continuing our survey in the Swan Creek study area. As reported in the previous update, we are revisiting Areas 1 and 2 (portions of the overall study area) to obtain a larger, more representative sample of the range of archaeological materials present. Although we have focused primarily on the 19th century components found in the study area, we have also noted the presence of much earlier prehistoric material. Unfortunately, with a few notable exceptions (reported here and here), most of the prehistoric material we have found consists of flakes (waste products from making stone tools) and fire-cracked rock (FCR). These items are not particularly diagnostic in a temporal sense.
Last week as Nick Bacon, Brad Jarvis, and I were plodding (and plotting) along in Area 2 recording artifact locations, including several flakes and FCR, I mentioned (probably several times… it was a long couple of days) that we had yet to find any artifacts that could help date the prehistoric component. Certainly, we were due for something diagnostic. We just needed a bit of luck… and no one has more luck than a beginner!
So, on Thursday, Nick, Brad, and I were joined by Roxanne Adamczyk. Roxanne has been a volunteer in the lab for several weeks now, but Thursday was her first ever field experience. I don’t think she was at the site for more than five minutes before she found a really nice corner-notched/expanding-stemmed biface! Although the age of this projectile point or knife is not exactly clear-cut, it probably fits with Feeheley-like or similar late Archaic period material from approximately 3000-4000 years ago (Lovis and Robertson 1989; Taggart 1967). Other prehistoric material from Area 2 includes another biface fragment (top row, right), two unifacially retouched flake “scrapers” (bottom row, left and center), and a bipolar core (bottom row, right).
Nick must have been inspired by Roxanne’s biface-finding prowess because, after moving over to Area 1 this week, he proceeded to find another late Archaic corner-notched Feeheley point (top row, center) and the base of a Middle Archaic side-notched Raddatz point (top row, right). We also found the base of a Late Woodland/late prehistoric triangular Madison point (top row, left). The Raddatz point likely dates between approximately 4500 and 6200 years ago (Lovis and Robertson 1989). Madison points and other similar triangular points were being used in this area from at least 1000 years ago right up to the Historic period. Other prehistoric items from Area 1 include a unifacially retouched flake “scraper” (bottom row, left) and two utilized flakes (bottom row, center and right).
We went from having no diagnostic prehistoric artifacts in either Area 1 or 2 to having Late Archaic material in both and, in addition, Middle Archaic and Late Woodland material in Area 1. Definitely a productive couple of weeks! We wrapped up our fieldwork in the Swan Creek study area earlier this week and are now looking forward to resuming our excavations at the Steltzriede Farm site in Saginaw Township. We expect to begin working at Steltzriede next week, so stay tuned for updates as that project gets underway!
