At the posted coordinates you will find a large pole with a flag way up high. The final stage for this cache can be found by doing a projection from the posted coordinates.
First count the the number of large bolts that are used to attach the pole to the concrete foundation.
Use the following to do a projection from the posted coordinates:
Distance : 9 + (1600 / #of bolts) meters
Angle : 7 + (2000 / # of bolts ) degrees
The last digit of the north coordinates is 3 and the last digit in the west coordinates is 5.
