Operator, Oh Could You Help Me Place This Cache? Mystery Cache

Darwin Awards for anyone who attempts this from the Highway. You can not reach this from any roadway! Use the suggested parking and Trailhead. NOT RECOMMENDED IN RAINY WEATHER

Cache is NOT at the posted coordinates. To get to the final you'll have to solve the puzzle then follow letterbox style instructions from the geochecker

The Posted coordinates are the closest parking and the trailhead is the easiest legal access to the cache.

Solve the puzzle to reach the reference point where your instructions from the geochecker begin. Seeing as GPS signal is hard to achieve here you'll have to stop and wait for your signal to return. To do this hold your phone higher!

If your coordinates are correct its just a matter of making the call to log your find. D rating is for the puzzle not the hide. Oh and BYOP!
