Congrats and thanks to the 26 finders over the last 7 years.
This puzzle required looking at the source code of the description and finding a GC code to the original Zeros and Ones cache. Then making a Grille Cypher by cutting out the "1"s in the original and lining them up with this puzzle.
Then converting the Zeros and Ones that are revealed from ASCII encoded binary to text to get the coordinates.
