Based on a popular puzzle, each column, each row, and each block of nine can only contain each number from 1 to 9 once.
The yellow blocks, reading left to right, top to bottom, will provide you with the last five digits of the North Coordinates.
The green blocks, reading left to right, top to bottom, will provide you with the last five digits of the West Coordinates.
Note: Coords may be a tiny bit soft. Try 20' at 333°.
The terrain is a lot tougher than you would expect in a town like Dover. Remember: You cannot fly, so don’t try it. Sticking to the trail is the safest. There is no need for any rock climbing or descending. Be careful! You will find yourself in an area of jumbled rock blocks going every which way. If your GPS tries to send you over the edge, don’t do it!
The container is a 6x6x3½“ Lock & Lock hidden in, by, and/or behind rocks. Please rehide it well.
