JoeRobe writes: Roanoke Colony (on the coast of North Carolina) disappeared sometime between 1587 and 1590, with the only clue to its fate being the word "Croatoan" carved into a wooden post. Now, as if straight out of an Indiana Jones script, new clues to the whereabouts of the lost colony may have been discovered on a 16th-century map. The British Museum has re-examined the watercolor map to find a hidden symbol under a patch, in the shape of a 4-pointed star. The star likely indicates the location of an existing or intended fort that the settlers may have retreated to after abandoning the colony. Adding to the mystery, the patch overlaying the star may have been added in order to hide it from the "spy-riddled English court."
