archaeologist excavates a rural field in Kansas and discovers the long-lost city of Etzanoa

Second Largest City

If we believe Blakeslee then the city just found could be the second largest city in North America. It all began in 1601 when a faction of Spanish conquistadors saw a large city. It was after a century, the French explorers came to the city but by that time the city had been destroyed by European diseases. The residents were dead and the city was desolated.
