I've driven this road a couple of times and marvelled at the man made features on the approaches. Passed by the other day on the way to somewhere else and took the chance to place a cache in order to let others share the experience.
The box is a very small click-lock box, with room for nothing much more than a logbook. The pen I had was even too big to fit in there. Feel free to drop off a pen and maybe some small trinkets or a small travel bug might fit.
