This is a Puzzle cache. Don’t go to the published co-ordinates, you will find nothing there, instead solve the puzzle to find the final location.
For this puzzle you need to link matching letters with a single line that can’t cross itself or any other line or go back on itself. All grid squares must have a line through them at puzzle completion.
Once completed you need to solve for the following:
S 41 1A.BCD E 173 1F.GHI
A = First digit of M
B = Equal to D
C = Sum of digits of H
D = Sum of digits of F
F = Last digit of B
G = Sum of digits of I
H = Second digit of L
I = First digit of M
Sum of A..I = 42. The cache contained a log and pencil at time of placement. No room for TB’s sorry.
