TheAwesomePenguins: I had a chance to stop by and look at this one. The cache container was there, but sadly it was at the very bottom of the inside of the stump. I was in up to my armpit and barely could get my fingers on it.
With all the construction going on right beside GZ I felt it safest to remove the cache container and archive this one. I don't want to see anyone getting into issues with any of the big trucks rolling around this area.
Container has been removed.
