Mysteries at the Monument: Ames Pyramid, Straus Titanic, Cracking the Zodiac

On a high summit near Laramie, Wyoming is a strange pyramidal structure that looks like something from ancient Egypt or Mayan Mexico. But this monument actually commemorates one of the greatest technological achievements of the 19th century and one of the worst scandals. In a peaceful park onManhattan's Upper West Side is a poignant statue commemorating a tragic love story that began in New York City and ended in the frozen seas of the NorthAtlantic, with the sinking of the RMSTitanic. Off the western shore of Lake Berryessa in Napa County, California is a strip of land that locals have dubbed Zodiac Island as a testament to its sinister past. It was here that two victims of one of California's most notorious serials killer were found.
