Jiu Dong Tian Caves, Arch in China

 

On our visit to China, we toured the Jiu Dong Tian Cave system by boat. We had to take a tour bus down the river, hike down the river to a bridge, cross over, then take another tour bus down the other side of the river, then hike down into a cave before boarding boats to continue on through the caves. We went under this huge arch as part of the hike down to the dock. For size comparison, you can see a picnic table with a red umbrella and people standing under it. After emerging from the cave, there was another dock where others could go on the tour by going upstream. Normally, we would've continued farther down river and taken another tour bus back, but recent storms caused damage downstream, so we ended up going back through the cave a second time by traveling upstream to the original dock.

The Chinese word for cave is "dong." The Chinese word for window is "tian." So where Americans might call this feature a natural arch, the Chinese often call these features a "cave window."

Qingxudong Arch, near Dafang, China, 7th largest in the world

 

Qingxudong Arch has been measured by laser rangefinder to have a span of 251 feet (76.5 meters) and a height of 246 feet (75 meters). That happened in 2015 by Natural Arch and Bridge Society member Gunter Welz. We used our own laser ruler when we visited on May 19, 2026, and basically confirmed those numbers. This arch had plenty of visitors and cars, vans, and even a small motorhome parked underneath. It's located near the village of Yang Chang Ba in Guizhou Province, China. In terms of span, the Qing Xu Dong Arch is considered the 7th-largest arch in the world. There's a small stream flowing under it. Beyond the arch, the stream curves into a cave and ends up going underground. It's very spectacular. The Chinese word dong translates to "cave" Instead of calling these features "natural arch", the Chinese tend to use either "heaven's gate" or "cave with window."

Yunmentun Natural Bridge in China, 16th Largest in the World

 

We went on a trip to China to view 9 of the world's largest natural arches and natural bridges starting May 17, 2026. This was the first one we saw on this trip, it is number 16 on the list. Instead of calling these features "arches", the Chinese seem to prefer using the term "gate", as that is the translation for the "men" part of the name Yunmentun. Altogether it translates as Cloud Gate Village. It's been measured at 213 feet (65 meters) for its span. We rode in a boat upstream on the Yongshui River, viewed the bridge from the river side, then went under the bridge to a dock along this tributary.

The Fire Wave in Valley of Fire State Park, Nevada

Another look at the feature called The Fire Wave in the Valley of Fire State Park, in Nevada.  You can reach it by a short hike from a well-marked trailhead. The rangers referred to it as their version of "The Wave." The hike was only about a mile and it was during spring break, so there were lots of hikers on the trail.  We had to wait our turn to get pictures of the "wave" without any other people in the picture. The outcrops in Valley of Fire consist of a mix of bright red Aztec sandstone and gray and tan limestone.

The Valley of Fire State Park is significant for all the Star Trek fans out there. This was the location where "Star Trek Generations" was filmed. This is the movie where Captain Kirk and Captain Picard meet and have to work together to defeat an evil scientist. At the end, Kirk dies and Picard ends up burying him.

Lexington Arch in the south end of Great Basin National Park in Nevada

Lexington Arch is a limestone arch in the southern part of Great Basin National Park in Nevada.  To get here you have to drive on dirt roads and then hike about a mile and a half on a rugged trail.  The fact that this arch is composed of limestone is very noteworthy, since most of the arches in the West occur in sandstone.  The fact that this rock span occurs in limestone may mean that it was once part of a cave that has eroded away.  Or it may be that the stream that carved Lexington Canyon carved this span when the canyon was much shallower, in which case this arch would actually be a natural bridge.
