Silkworm cocoons found at Cahokia's Monks Mound by Sutter in 1920 are now held by the Madison County History Museum with roughly 3,000 other artifacts, including arrowheads and pottery. Thomas Remy owned Monks Mound from 1860 to 1880 and preserved artifacts. The cocoons remain undated. The video argues that they may call into question the conventional understanding that no silk culture existed in America before the French arrived in 1700. It also reports that mulberry trees were documented at the site and that a single cocoon contains a continuous 1,500-meter silk filament. AMS radiocarbon dating costs $675 per test, while amino acid racemization testing costs $3,500 for 10 samples.
