Two hikes at Pinnacles NP.
Hiked up and around Pinnacles. Spectacular rock formations and impressive CCC work to build rock stairs with iron railings as needed. Then tried "easy" cave and cliff trail -- much more rigorous than expected. Cave dropped at least 100' as it followed the canyon and stream. Big steps down, narrow passages.
Met ranger just after shutdown ended but by policy shutdown must be for full 24 hours so he could not unlock restrooms etc. But free for all visitors today!
