The coordinates above will take you to a parking area. Once there, you will see a plaque. You will need some information from this plaque to calculate the coordinates for the final cache location. At this location, you will find an ammo box.
FINAL LOCATION - N 43 40.BAB, W 073 46.CCD
A = the first digit of the year that the project was completed.
B = the number of people in memoriam PLUS the number of town supervisors.
C = the number of letters in the name of the lake mentioned.
D = the number of towns involved in the project MINUS the number of town supervisors.
There is some tree cover at the final location, but the final coordinates were an average of 247 readings on my GPS. Please make sure that you rehide and cover the cache well after you find it.
