To claim this find, you will first have to solve this puzzle (Flash required).
Once you have completed the puzzle, you will receive a congratulatory message along with a number. To find the cache, divide the number by 1,000 then add to this meaningless coordinate: N43 46.019 and (after division) subtract the number from this meaningless coordinate: W079 14.894. You can use the Solution Checker to verify if you are correct.
The container is hidden at the calculated coordinates, and is very close to what is in the puzzle image.
