So, with my southeast Arizona exploration trip in mind, I researched the place. There was plenty of info about the Chiricahua National Monument, which is a small part of the Chiricahua Mountains. And between various camping/hiking websites and the Forest Service I learned about other places to camp in the area, both boondocking and campgrounds—mostly on the west side of the mountains. Since I would be coming from the west, it made sense to go to the camping areas on the west side. But I'm sort of a contrarian, so I decided to loop over the north end of the range and enter from the east, through Portal.
One of the campsites in the canyon was closed, another was small and full and had too much solar-unfriendly tree coverage. But I nabbed the last campsite at Sunny Flat campground, which was both sunny and flat.
I wished I had a geologist handy to explain the greenish yellow color of the rocks and how these caves were formed.
I stayed two days, which is something for me, especially considering there's no cell signal in the canyon. But I'll be back, maybe in the autumn when the leaves are changing.
