Archaeologists have uncovered two large piles of iron flakes on North Carolina's Hatteras Island that they say are evidence of a 16th-century "Lost Colony" of English settlers who disappeared in 1587. But some experts are unconvinced and say more evidence is needed.
"We've been digging there for 10 years off and on," Mark Horton, an archaeology professor at the Royal Agricultural University in the U.K., told Live Science, "and I think the real breakthrough was the hammer scale mixed in with 16th-century artifacts."
