At the posted coordinates you will find a small structure with information imprinted into the concrete about 2 meters off the ground.
From the imprint assign the following:
A = the number of words in the first line on the imprint
B = the number of words on the second line on the imprint
C = the number of words on the third line on the imprint
D = the number of words on the fourth line on the imprint
The fifth line is a phone number but you won't have to use it.
The difference between A and B is 2. The difference between D and C is 2.
North : 43 ((10 x A) + (A x D) + C).((100 x A) + (10 x B) + (A x B))
West : 079 ((A x D) + 6).((20 x D) + (B x 9))
The last digit in the north coordinates is 8 and the last digit in the west coordinates is also 8
