Though I'd planned on doing the series in order, I stopped here first because it was kind of apart from the rest.
Garmin pinpointed GZ as an old rotted log that had been torn apart by something or someone, but found no cache.
I decided to do the rest of the series and then return with a better idea of what I was looking for.
Upon my return I got the same results even though I spread out quite a ways. I then took out my smart phone and used that. It took me to the exact same GZ.
Thank for the exercise.
