This is a bonus cache to the nearby Adventure Lab walking tour.
If you haven't completed the LAB caches, scan this code to do so. You will need the "Adventure Lab" app on your phone to play.
You must should complete the five lab caches to be able to locate this one.
Once you are at the secret coordinates look for a date plaque. (Not the obvious one!)
To get your northerlies:
Add the 4 digits of the date(A,B,C,D)
and multiply the sum by the number of gargoyles you see.(X)
(A+B+C+D)*X= Z
Take that total (Z) and add the last digit of the year (D).
Z+D=TOTAL
Subtract this total from the north coordinates that brought you here.
To get your westerlies:
Add the 4 digits of the date(A,B,C,D)
and multiply by eight
(A+B+C+D)*8 = T
now add 10 to that
T+10=TOTAL
Subtract the total from the west coordinates that brought you here.
Checksum= 165
The checker will give you a trail head to begin your short walk.
