Missing in Aurora Adventure Lab Bonus
You will need the information from all five of the journals in the Adventure Lab, including the associated pictures. Picture details can be more easily examined by tapping an image while in journal view and then zooming. Don't forget to go back and review the final journal, which is bypassed when you first complete the Adventure Lab.
Each journal is a 'what's missing' style mini-mystery with a one-letter answer. Concatenate your answers as a single string of 5 letters (Mini-Mystery #1 -> Mini-Mystery #5) and enter them into Certitude to receive the final coordinates of this cache.
You can validate your puzzle solution with
certitude.
A commemorative pathtag awaits each finder of this bonus cache as a special reward for completing the tour and playing the "Missing in Aurora" game! If you'd like, please post pictures of yourself at one or more of the AL stops and feel free to rate/favorite this bonus cache based on your experiences on the Adventure!
