I don’t normally share my professional work on this blog but thought it might be of interest. We were out re-recording a rock shelter yesterday known for some rather mysterious pictographs. Mysterious in that they are vague and probably mostly wiped out due to weathering. Only the protected portions of the shelter contain clear images and only one image is a petroglyph (pecked as opposed to painted).
Looking for hidden glyphs.
There are no clear cultural symbols that would tie these panels to a single time period or affiliation but there are some hints at an Archaic connection (or at least stories about the Archaic). It is strongly suspected that the site has been known and has been collected on for at least two centuries as Europeans had a presence here since the early 18th century. This may account for the complete lack of diagnostic artifacts on the site. However, diagnostic points have been collected nearby and show a strong association with the Missouri Late Archaic tradition in the form of Langtry points.
Hope you enjoy some vicarious archaeology.

Thank you, interesting glyphs.
