The best way to get to GZ is to get a raft from the nearby river grab onto a tree and hold on for dear life while climbing while trying to avoid the vicious rapids. Then you will find a cave with dangerous animals leaking in the cave. Once you cross the bridge (which is hanging by a thread) you will have to play a game of the floor is lava and avoid the steaming hot lava pit below you. Then you will do the complete and cross a lake of thin thin ice that you will try not to fall in. Then you will reach a little river where you must whistle for the guide (don't look him in the eyes...) Once you reach the destination you will have to slay a dragon that's guarding the cache. Once you kill the dragon you will find some sort of metal pole.
Now for a small bit of truth...
1. The cache IS at the posted coordinates.
2. You WILL NEED a writing tool.
Big thanks to thewilliams_6 for even making this cache possible
