I'd been considering placing a cache here for some time, and after archiving my original Wet and Dry recently I decided this would be a good replacement.
It's not difficult finding the cache, but getting to it is not so easy! There are a number of ways to approach, the parking indicated is best for the easiest access, but there are other ways.
FOR YOUR OWN SAFETY DO NOT ATTEMPT TO GO DIRECTLY DOWN FROM THE TRACK ABOVE OR ATTEMPT TO REACH THE CACHE IF RIVER LEVELS ARE HIGH!
The terrain rating can vary due to time of year and weather conditions, I've made it a T5 as during winter or during bad weather it can be close to impossible, however you may be lucky at other times and be much easier (relatively). GPS reception can be poor at GZ, but its not too difficult to spot the cache.
