Nuestra Señora de Atocha

The account

In September 1622 the Nuestra Señora de Atocha, a treasure galleon riding low with the silver of the Spanish empire, was driven onto a reef in a hurricane off the Florida Keys and sank with two hundred and sixty souls and a manifest that read like a fever dream: twenty four tons of silver, gold bars, and a chest of Colombian emeralds. Spanish salvors found her quickly, then a second hurricane tore the wreck apart and scattered her across the seabed, and for three hundred and fifty years she was gone.

Then came Mel Fisher, who said the same four words into the radio every single morning for sixteen years: today's the day. It cost him everything. In 1975 his son Dirk found the first bronze cannon, and days later Dirk and his wife drowned when their salvage boat rolled over in the night. Fisher buried his son and kept searching. On the twentieth of July, 1985, his divers swam down onto a reef of stacked silver bars and chests of coins, the mother lode, four hundred and fifty million dollars of it, gold chains and emeralds the size of knuckles.

It was the richest shipwreck recovery in American history, and it still does not add up. The manifest lists treasure that the mother lode never accounted for, because the sterncastle, the high rear of the ship where the registered gold and the very best cargo rode, was never found.

That is the part that keeps the boats out there. The Fishers got the body of the Atocha but not her richest room. Somewhere off the Marquesas Keys, in sand that shifts with every storm, a chest of the finest emeralds and perhaps a thousand pounds of gold are still lying where they fell in 1622, and the people who found the impossible are still looking for the rest of it.

Known intelligence

• The Atocha sank in a hurricane off the Florida Keys on 6 September 1622 with about 24 tons of silver, gold, and emeralds and some 260 lives.
• Mel Fisher searched 16 years; his son Dirk found the first cannon in 1975 and died days later when a salvage boat capsized.
• {'On 20 July 1985 Fisher\'s team found the "mother lode"': 'silver bars, over 100,000 coins, gold, and emeralds worth about 450 million dollars.'}
• The sterncastle, holding much of the registered gold and the richest cargo, has never been located.

Theories of the hunt

• The missing sterncastle and a second debris trail lie scattered nearby, still holding the best of the cargo.
• Storms in the 1620s spread the wreck so far that part of it may never be found.

Leads, where the trail points now

• The mother lode was found in 1985 off the Marquesas Keys, but the sterncastle, holding much of the registered gold, has never been located and is the live target.
• Mel Fisher's Treasures still works the site under admiralty rights; the corridor runs along the wreck's scatter trail toward deeper water and a suspected second debris field.
• The 1622 to 1626 Spanish salvage records and the ship's manifest let salvors compare what is recovered against what is owed, which pinpoints the missing cargo.
• Storms keep reburying and re-exposing the scatter, so the method is patient magnetometer survey of the known trail rather than a new search area.

The trail, in order

• 6 September 1622: the Atocha sinks off the Marquesas Keys.
• 1622-1626: Spanish salvors recover little before storms scatter the wreck.
• 1969-1985: Mel Fisher hunts the Atocha, losing three crew.
• 20 July 1985: the mother lode is found; the sterncastle is not.
