A ten-inch golden statue discovered in a cave near Bogota may be the key to the greatest treasure never found: El Dorado. For centuries, rumors of a "Lost City of Gold" attracted explorers and fortune hunters to the Colombian Andes in search of riches. Now, after 500 years of futility and bloodshed, investigators try to finish the job, using the found statue, a beautiful model of a golden raft, as their guide. See legend and fact collide as we apply forensic techniques and decipher ancient documents to uncover the truth behind the myth.

The Vinland Map was allegedly created 50 years before Christopher Columbus set sail, but amazingly, it features the coast of North America.

They'll test the theory that the document is based on Viking maps created centuries before Columbus was born, and they'll name a 1930s scholar who may have faked the whole thing.
