In 1938, Matthew Stirling made his first field trip to Mexico and learned of a giant head half-buried in a field at Tres Zapotes — the same head José María Melgar y Serrano had discovered in 1862. With Smithsonian backing, his 1939 expedition mapped the entire ancient city and unearthed a second head nearby. No proper roads existed — only muddy horseback paths.
