America Unearthed (2012)

S1E5 A Deadly Sacrifice

A man arrives at Scott Wolter's lab with a hefty 500-pound find—a massive boulder he extracted from the Arkansas River, marked with an enigmatic bull symbol. As Wolter delves into the origins of the carving and its potential ritual significance, he uncovers links between the ancient Egyptian Apis bull cult, the obscure Mithraic religion, and a group of pre-Columbian explorers in Oklahoma's panhandle. Ultimately, cave carvings from America's Heartland provide insights into an ancient connection, suggesting that a faction of religious outcasts may have reached America long before Columbus.
