Word Wheel #6 Mystery Cache

NOTE: The listed coordinates are NOT the position of the cache. You must solve the puzzle below to determine the actual coordinates of the cache.

I first encountered this puzzle format among Eric Berlin's Puzzlesnacks.  As you'll see, this one employs a small new wrinkle.  Enjoy!

If you wish, the puzzle is also available to download and print as a PDF.

As the cache owner, I do solemnly swear that this file is safe to download, although it has not been checked by Groundspeak or the reviewer for malicious content.  Download at your own risk.  But really, it's just a PDF hosted on Google Drive that any modern browser will display for you just like any other webpage.

Each answer in this puzzle uses either five or six letters stretching from the numbered space on the outside ring inward to the center — but the letters in those words will appear in a scrambled order.  It’s up to you to logically place the letters into the correct spaces so that all 24 answers can be made.  The extra wrinkle here is that the highlighted grid spaces contain two letters each.  In answers that use the highlighted grid spaces, those two letters will always be adjacent to each other in the solution, but not necessarily always in the same order for each answer.  After completing the wheel, enter the letters in the outer ring (1-24) into Certitude to obtain the final coordinates.

You can validate your puzzle solution with certitude.
