Once again I am showing my lack of originality, by stealing an idea from a puzzle magazine; but of course changing it to make it much harder for you super-intelligent geocachers. (Obviously the next step up in the chain of human evolution.)
You simply need to place the 12 words provided into the 12 white rectangles in the image below. The question marks indicate categories common to the two (or three) adjacent words. So you can see that 10 of the words will each fit into two categories, and two words will each fit into three categories. (The original puzzle provided the categories, and the solver had to find the words. But I thought this seemed more interesting.) You won't need to find the exact wording of each category; just close enough to make the links.
With all of the words placed properly, you will be able to form two common seven-letters words going around the two inner circles, in the direction and starting/ending as indicated by the arrows. The numbers beside each small circle indicate which letter to use from the adjacent word in order to form the seven-letter word. For example: The bottom word begins in the bottom small circle. If the word at the very bottom of the diagram was "CRICKET", then "C" (letter #1 of CRICKET) would go into that small circle as the first letter. If the next word going around clockwise was "PINTO", then "T" (letter #4 of PINTO) would go into that small circle as the second letter, etc, etc.
To turn all of this mess into coordinates, here is the final step: For the top seven-letter word, for each letter, take the position number of that letter (1 thru 7) and multiply it by the "letter-to-number" converted value of the letter (A=1, B=2, etc). This will give you seven numbers. Add those seven numbers together, and add that value (divided by 1000) to the posted North coordinate. Do the same for the bottom seven-letter word, then subtract that result from the West coord.
That's all there is to it!
