Step 10: Collect the ten letters found at the left and east sides of clue 3.
Anagram: I LIE HIDDEN AT OVERTURE
Step 11: Collect the letters that are 'overture'--over T, U, R, and E.
Over T: A E E S N A E
Over U: S S T F
Over R: N E W S U R E
Over E: C E Z L G I A V H F R R U R I
FIVE FINGERS = Z
TREASURE ANSWER HAS CLUE
The trick to this step is to realize that 'Five fingers = Z' is a reference to a specific page inside the book--one that has a 'treasure answer'.
It's page 44--the dragonfly puzzle page.
The fairy's fingers are displayed as 5,5 which are the coordinates for the letter 'Z' from our original 5 x 5 grid.
The 'treasure answer', RICKETTS GLEN SP FALLS TRAIL SIGN, is the final set of letters to anagram.
Before I tackle that anagram, there is another, final set of letters in the 10 x 10 grid.
Step 12: Collect the unused letters of the 10 x 10 grid.
At this point, every single letter of clue 3's 10 x 10 grid has been used except 12:
R I E N A L A N G C W S
Anagram: ANSWER: ALIGN C
I find it very pertinent to note that the letters for this anagram are not discovered until AFTER you have completed all the other anagrams and already found what appears to be the final puzzle and the final solution to clue 3 on p. 44 in the book.
Step 13: Final anagram puzzle.

PARK'S LG TRAIL SIGN

This final solution reveals the location within the park containing the token as well as an announcement that there are additional tokens to be found.
