Priest Lake
This is a bonus cache that is intended to call attention to my Priest Lake History Adventure. After completing each of the five Adventure Lab locations you will see a number associated with a letter in the journal. Once you have visited all five spots and completed the lab there, you will have all of the information you need to calculate the final coordinates of this cache.
N 48° 3A.ABC', W 116° 5D.ACE'
The start of the trail for accessing the cache can be found by subtracting 0.017 from the latitude and adding 0.169 to the longitude (using the corrected coordinates).
