Cache is recycled from the final stage for my cache 'Rounding A Squared Cube'. Unfortunately, the field puzzle went missing for that cache and is not easy to re-create. It's a fairly easy walk in. Stay straight when the trail turns right. Foliage can be dense in summer time. When at GZ, do not attempt to go directly down (go around instead). Your feet have a good chance of getting wet.
You are not obligated to attempt this cache. Do so at your own risk. Be mindful that hunting is allowed in the area so wear orange during hunting season.
