The Story

Colonel Percy Fawcett, his son Jack, and Raleigh Rimell entered the Brazilian Amazon in 1925 seeking what Fawcett called the City of Z. After a final dispatch from Dead Horse Camp, the party vanished. Dozens of rescue missions and over 100 subsequent deaths among searchers have failed to locate remains or confirm their fate.
