Onyx Bridge Professional Review and Guide
"Situated in the starkly beautiful northern region of Petrified Forest National Park, Onyx Bridge is one of many petrified logs strewn across this desolate reach of Arizona. It earned its name because it spans a small wash. Certainly as interesting are the countless other pieces of fossilized wood found along the hike. Most of this hike falls within an established wilderness area, and the hike mostly cuts across open terrain rather than following an actual trail."
--Scott S. Warren, 100 Classic Hikes Arizona (The Mountaineers Books).
Interesting hike but a difficult place to find. The ranger at the Painted Desert Inn could not point out any landmarks. Fortunately, it was in my GPS as a POI and after searching for awhile, I used the GPS to lead me to Onyx Bridge. The area is very desolate and when I was there there were no other people to be seen.
