The cache is not at the posted location and there is no need to go there.
You are looking for a micro cache that can be found at the following coordinates:
50 (JU+PM).(GJ+PBD-HH)(JU-DN)(NKa-NKr) North
1 (SM-HH).(DN-MB-DJ)(JA-NP-DJ)(SC-SD-LD) West
GZ is a very busy location during the daytime - stealth will be required.
When returning the cache please ensure it is wedged securely in place and make sure the cap is on tightly. Happy hunting!
