Cache is NOT at posted coordinates.
This cache is a BONUS cache that requires you to run the Adventure cache in order to find the cache and log book. In each of the five labs Journal you will be given a letter in the format "CODE: X". Once you have all five letters, unscramble them to form a five letter word. Input this word into the solution check and if correct you will be given the coordinates to this cache.
