This is a puzzle cache. Do not go to the posted coordinates. Solve this puzzle to find the final coordinates.
And now for something a bit different. Perhaps you have seen something like this, perhaps you have not. I originally put this out to be a companion cache for an event. That event is passed, but the good vibes linger on. Thank you to all who attended that one and any of my little events.
This geo checker is not looking for specific coordinates, so don’t start trying to find numbers in this text. You will need to enter a string of fifteen letters.
To get you started, I have provided a few examples:
Inquisitiveness
Conservationist
Pedestrianizing
Personification
Electrodynamics
Distinguishable
Mischievousness
Procrastination
It is one of those? Maybe not? (The Shadow knows!)
Put the 15 letters into the checker – no capital letters and no spaces. Good luck. The final coordinates will appear in the checker once you have given it the correct string of letters.

You can validate your puzzle solution with certitude.
