Savage Divide treasure maps

The Savage Divide treasure maps are a set of notes in Fallout 76. They lead to buried mounds hidden throughout the Savage Divide, all of which contain random valuable loot.

The notes can be found throughout Appalachia, as randomized, rare loot in containers or on the bodies of Boss creatures. The treasure maps lead to:
