Abstract of Information Available

Human remains representing, at least, one individual have been identified. No associated funerary objects are present. These human remains were discovered by a private citizen who saw them on display at the Okoboji Antique Mall in Arnolds Park, IA and reported them to the UI OSA in late June 2026. The State Archaeologist saw to their transfer to the OSA in early July 2026. Handwriting on the human remains suggests they were exposed by gravel quarrying at “Trumble Lake” in 1950. This is likely a misspelling of Trumbull Lake, which is near Arnolds Park, and has several burial sites documented near the lake's southeastern shore. Site [redacted] is the most likely origin of these human remains as it is a gravel quarry where human remains have been previously documented as exposed during quarrying activity. Projectile points were also reportedly encountered but diagnostic types were not described. One adult male is represented (BP4058). No hazardous substances were used to treat the human remains.

Cultural Affiliation

Based on the information available and the results of consultation, cultural affiliation is reasonably identified by the geographical location or acquisition history of the human remains described in this notice.
