Cache is not at the posted coordinates!! I’ve been there but you can’t go there and if you could you’d likely find nothing except a couple of lawn chairs and an ashtray.
In other words, this is not where you will find the cache. To solve the puzzle and find the corrrect coordinates for this cache you have some learnin’ to do. By the way Igneous is Bliss, but Metamorphically Speaking we should avoid being Definitely Sedimentary.

CONGRATULATIONS, GRIZZLYCACHER FOR THE FTF!
