(Difficulty rating is based on completing the adventure lab rather than trickiness of the hiding spot).
5/1/23 update: Due to a number of complaints about this bonus cache, we have simplified the method for solving for the final coordinates. The cache is still located in the same spot, which is NEAR THE WESTERN END OF THE SPRINGWATER CORRIDOR (in case this affects the order in which you visit the adventure lab locations). Posted coordinates are a possible parking location for the Adventure Lab and for the Bonus Cache.
To find this cache, substitute the numbers provied in the Adventure Lab journal for the letters below:
N45 25.ABC, W122 23.DEF
