The cache is NOT at the published co-ordinates and you do not need to visit them to find it.
In order to find the first tree you need to construct and then solve a fairly tricky Sudoku puzzle. You will need to know the rules of Sudoku and how to logically solve some simple algebra maths equations.
Stage 1 - Constructing the Sudoku
To construct the Sudoku, you need to find the value of the following 8 letters: A, B, C, D, E, F, G and H and then substitute the numbers for those blue letters in the following Sudoku grid.
Each of the 8 letters (A, B, C, D, E, F, G ,H) represents a number between 1 and 9. All the 8 numbers are different from one another. Obviously because there are 8 out of 9 there is one number missing, but some Sudoku's are like that. I said it was tricky.
- E = H Minus D
- B = H to the Power of 2 Minus D to the Power of 3
- D = Square Root of D
- A = G Plus F Where G Less than F
- C = D Plus E Times H
- H = Square Root of A
Stage 2 - Solving the Sudoku
Having substituted the blue letters for the results above you should now have a standard solvable sudoku puzzle with 27 of the 81 squares filled with numbers. Six of the other 54 squares contain the red letters J, K, L, P, Q and R. Once the puzzle is completed, you will have numbers (between 1 and 9) in each of the squares that have red letters in them. Not all these numbers are different.
The co-ordinates of the first tree are: North 83 63.JKL', West 337 31.PQR'.
Substitute the red letters for numbers in the Sudoku grid to find the cache location, once you have given it a little rotation.
Take note of the attributes and D/T rating, more than just a GPS required. It may take more than one visit if you don't have all the required equipment.
As with all mystery/puzzle caches, please do not disclose solutions or locations in your logs, nor, pass on solution to others. Thank you
