Stuart, in his book Ancient Pioneers ​ — The First Americans, states: “To many archaeologists and art historians, the platform mounds, carefully arranged around plazas, ” and some of the pottery“ demonstrate clear influences, perhaps indirect, from Mesoamerica — ​ as do the strains of maize and beans present at the sites. ”
Stuart kirjutab oma raamatus „Ancient Pioneers – The First Americans ”:„ Paljude arheoloogide ja kunstiajaloolaste sõnul näitavad väljakute ümber rajatud platvormiga maundid [ja mõned saviesemed] ning sellest paigast leitud mais ja oad selgelt Mesoameerika kaudset mõju. ”
