The cache isn't at the posted coordinates. The degrees and minutes are correct but you need to solve the 3D maze below to find the decimal minutes.
Please don't disassemble what you find at GZ. As you can see I had to fix it even before getting the cache out. You can always slip a piece of paper with your moniker inside. I've even left a small pad of paper. I do encourage those that do succeed to brag in their logs and claim their superiority. Or something like that.
Back to the puzzle, the mazes A to F (top to bottom) form a 3D maze. The squares with a black dot connect with the square with a hollow dot the level below (and vice versa you can go from a hollow dot to a black dot in the level above). Start at the top left corner of A and exit on the bottom right corner of F. Remember the expression the journey is more important than the destination? Sometimes it's not. Cache is located at N 47° 42.ABC W 122° 14.DEF
Congratulations to Stinson HQ on the FTF!
