A new puzzle type: this one is a traditional crossword with another puzzle inside it. These puzzles are known as "meta" puzzles. The solution to this meta-puzzle is a 7-letter word/name. Enter it into Certitude to obtain the final coordinates and a hint.
If you prefer solving the crossword on your phone or tablet or computer, I provide it here in Across Lite format. You'll still need to do the meta using the solved crossword.
