God of War has 12 Treasure Map Locations and Dig Sites. Using all treasure maps to find the dig spots is needed for the Treasure Hunter trophy. None of them are missable, you can still get the treasures and maps after the story in free roam.

The video below shows all them and can be collected in any order. If you can't reach one of these spots you must progress further in the story. It's best to collect everything after beating the game. They give a lot of hacksilver (Money) and rare crafting materials!
