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:
- Map #01 leads to AMS testing site, on a hill next to a blocked off tunnel.
- Map #02 leads to the cabins near Hornwright air purifier site #01.
Map #02 was previously labeled as #07. This was patched so the maps were consecutively numbered.
