I walked past here on the way to Kitty Hawk Down, and wondered why this was here. It must have had some function some time in the past, but now seems to be doing its best impression of a rather large outdoor planter.
The cache is not hidden in or around the planter, you need to look slightly further afield, and hopefully you have saved some strength in your arms to get to GZ. You should be able to do so quite safely, and there are a couple of natural hand holds that will provide some assistance.
The cache is a camo'd 2 litre container with room for swaps and bugs (the travel variety), please bring your own pen.
