The Aztec imperial treasury, dropped in flight
Last known, where the trail went cold
Fleeing the city on the 'Sad Night,' Cortés's men sank under their stolen gold in the lake causeways, a massive gold bar dredged up in 1981 was confirmed in 2020 as Noche Triste loot.
The account

The conquistadors loaded themselves with an empire's gold and ran for the causeways in the dark. The lake took the greedy first. The city above the lakebed is now one of the largest on Earth, and every metro excavation and sewer trench digs through the night the treasure drowned. One bar has already surfaced. The rest is under traffic.
