To get the coordinates for the final cache, you need to find the common name for, fagus sylvatixa f. purpurea. Example: juglans nigra = Black Walnut.
Take the number of letters in the first part of the name, in this example, Black, 5 letters = X.
In this example take the second part of the name, Walnut, 6 letters = Z.
Using fagus sylvatixa f. purpurea, find the common name of this tree.
For X in North coordinates, add 1 to the number of letters in the first part of the name: N42 19.X60. For Z add 2 to the number of letters in the second part of the name: W72 37.Z95.
At the coordinates above, not far from the final cache area, is a Massachusetts State Champion fagus sylvatixa f. purpurea.
