THE CACHE IS NOT LOCATED AT THE POSTED COORDINATES
To find the final for this mystery cache, you will need to complete the Adventure Lab "The Murals of Carthage". After completing each of the 5 lab caches, you will see numbers for the final coordinates appear. After the 5 lab caches are complete, combine your answers to form the final coordinates.
The cache difficulty reflects the difficulty to get the coordinates, not the hide. The terrain reflects the hide. This cache has been located further away from the AL than what one might expect in an attempt to get cachers to try to find other caches in the area.
Congrats to BeautifulRacket on FTF.
