No cache here at the posted coordinates.
I provide you with 22 images. Your job is to add a letter of the alphabet (as it's pronounced) to the front of each word. For example, if one of the images was of a tray, you would add a B to that to get B-Tray (betray). All letters except H, Q, W and Y will come up exactly once. Once you have all of the words figured out, put the string of letters you added to the starts of the words in order into Certitude. There is a geocaching-related word in the string of letters to help you confirm you're on the right track.
You can validate your puzzle solution with certitude.
Congratulations to JuniorWences on FTS and hohenschuh on FTF!
