Carved Rockford tablet discovered in 1874 Illinois mound near Rock River. Found in 1874 near Rockford, Illinois Located 6 miles from Rockford on high ground above the Rock River Mound was about 30 feet across and 8 feet high

In 1874, a small white carved tablet bearing 14 mysterious symbols was unearthed near Rockford, Illinois, about 6 miles from the Rock River. Found beneath a thin seam of decayed pottery at roughly 6 feet deep in a 30-foot mound, the hand-sized artifact featured a sun-like face, coiled serpent, lizard, and dagger marks. Researchers initially mistook the material for gypsum before reclassifying it as "Niagara spar." Stone tools and a pipe fragment lay beneath it. Its authenticity and meaning remain debated today.
