It’s been pointed out to me this puzzle doesn’t work as originally published
Accordingly, I’ve altered the elements to ensure it does work.
Apologies, this was one of my first puzzles. Phronimos
The actual cache is located at S 39° 0A.0BC E 174° 0W.XYZ where
A = 49, B = 93, C = 10
W = 39, X = 91, Y = 96, Z = 4
Checksum of A+B+C+W+X+Y+Z = 29
This track has got significantly shorter and very overgrown over the years
