From our experience, this cache requires you to bring along at least 80oz of water. Sometimes more is not better, it's just more. In this case though, more is better. Bringing a partner is strongly encouraged to complete this cache. Once you've arrived at GZ, the principal for gathering coordinates for the final should present itself. Good luck!

Unfortunate addition to many of our cache pages as of 2018: PLEASE REPLACE THIS CACHE AS FOUND! Unless you find it obviously out of place and in danger of going missing, we hid the cache where it was intended. Replacing caches differently than they were intended changes the experience for other cachers. Worse yet, intentionally or unintentionally breaking caches destroys the experience for your fellow cachers and makes owning caches difficult. Our caches should never ever require you to use a hammer, screwdriver, pliers, or prybar. If a cache is frozen in place, GENTLY, find a way to extract. And to everyone else, thank you so much for finding our caches. Your enjoyment of our hides makes it all worth the while.
