At the posted coordinates you will find a post with a red 2 digit number on a black background and a 5 digit yellow number following the letter P on a black background. The final stage for this cache can be found by doing a projection from the posted coordinates.
A = the 2 digit number
B = the 5 digit number
Use the following to do a projection from the posted coordinates:
Distance : [ (A + B - 9) / 76 ] meters
Angle : [ (A + B - 69) / 64 ] degrees
The last digit in the north coordinates is 1 and the last digit in the west coordinates is 5.
