To find the cache, you need to follow a few steps!
Step 1- Locate The Jellyfish!
Step 2- From the red dot on my photo, draw a line of 1.45 kilometers at a bearing of 158 degrees. There is room at this point to park your car.
Step 3- At this parking location, you will see a large object with some white numbers and letters painted on the side. Label the numbers ABCDE.
Step 4- Using the following formula, work out the cache location.
N51 3B.(E+B) (D-B) E
W001 3(D+A).(E-B) A (D+C)
Step 5- Head off to find the cache.
