The Cache
The cache is not at the listed coordinates. You are looking for a custom-themed container a bit larger than a mint tin. Bring your own pen.
The Puzzle
Another triangular puzzle in this series. This variation consists of six large coloured triangles with digits 1 through 9 each placed once into the triangles within. Additionally, every line (of length 9, even uncontinuous) contains every digit not more than once. Note - the row on the outer edge includes the cell on the nearest sharp end of the figure.
Perform number substitution to find the location of the cache, which is at
S 34 59.ABC E 138 45.XYZ
Good luck.
