The Treasure Map from Salt Lagoon points to a buried chest tucked away on a tiny islet north of New Bone. You first collect the map in northern Gibara, then sail to New Bone to dig it up. The whole run is short once you know the two exact spots.
Quick answer: Loot the map from the corpse at roughly 722,607 on the northeastern shore of Salt Lagoon (Gibara), then dig at 407,94 in the center of the small islet north of New Bone, surrounded by rocks and palm trees.

The chest is buried on a small piece of land separated from the rest of New Bone, in southwest Serranilla. The dig spot is at 407,94, north of the Viewpoint. When you pull into the docks, the islet is on your right, with a windmill on the hill ahead of you.


Rewards for the Salt Lagoon treasure
| Reward | Amount |
|---|---|
| Reales | 2,500 |
| Maize Deity | x1 |
Opening the chest hands you 2,500 Reales and the Maize Deity. You’ll know it worked when the loot prompt appears, and the treasure map is cleared from your active tracker.

Quick reference for both locations
| Step | Place | Coordinates |
|---|---|---|
| Pick up map | Salt Lagoon, northern Gibara (corpse by camp, north of Rowboat) | 722,607 |
| Dig treasure | New Bone islet, southwest Serranilla (center, near Rowboat, north of Viewpoint) | 407,94 |
If the dig option doesn’t appear at the islet, you’re likely standing there without the map in hand. Return to Salt Lagoon, loot the corpse first, then come back to New Bone and the chest will be ready to unearth.
