This is Yurok land and an old road being reclaimed by nature, especially thimbleberries! We learned about this spot from a previous geocache so we created something to keep the location known. The path can get bushy during certain times of the year but if you want it bad enough you can push them aside and claim your smiley. Just passed GZ you can discover more evidence of the old road, have a look around.
Cache has some appropriate camo, best to squeeze the container to open it, and byob pen!
