Columnar Joint Scenic Area

柱状节理景区

On the banks of the Longchuan River in Tengchong County, Yunnan Province, stands a large columnar crystal formed by the condensation of magma that was ejected during a volcanic eruption and was not exposed to the surface. In geology, it is called "columnar joints", and the locals figuratively call it "Divine Pillar".
The "Shenzhu" is the largest, best-preserved, and youngest columnar joint discovered in my country to date. The volcanic magma erupted at a temperature of 1200°C. When it cooled to 800-900°C, it crystallized and formed columnar joints. Because the magma contains hexagonal prisms of minerals such as plagioclase, olivine, hornblende, and pyroxene, these hexagonal prisms formed upon cooling are known as columnar joints.

The columnar crystals formed by the solidification of magma are vividly called "God Pillars" by the locals. This type of geological formation is extremely rare and truly a wonder. Looking up close is somewhat oppressive, like a grinning god or demon in a play, scarred and pouncing upon you. One cannot help but marvel at nature's marvelous handiwork. The drive from Heiyu River to the columnar joints takes about 5 minutes, but it took us over 20 minutes on foot. The journey was like climbing a mountain, crossing hills and ridges, with shaded forests and vast, open plains. Even in the shade, sun protection is still essential. The UV rays that peel off your skin are truly devastating. We almost gave up, feeling a little hopeless, but looking back, it was a truly special experience. As we reached the last step, we turned and gazed at the distant mountains and forests, spotting a prominent patch amidst the lush greenery.

The magma ejected during a volcanic eruption, which remains unexplored, reaches temperatures of 1200-1500°C. When it cools to 800-900°C, it is squeezed by its own movement or rapidly cooled by water, forming a remarkable array of regularly arranged volcanic rocks. Because the magma contains hexagonal prisms of minerals like plagioclase, olivine, hornblende, and pyroxene, 80% of the large rocks formed after cooling are hexagonal prisms, with some also forming pentagonal and quadrangular joints, hence the name columnar joints.

By Playing around |

The columnar joints look ordinary, but you can see the Gaoligong Mountains in the distance, which stretch like a wall across the horizon. The majestic mountains make people imagine that there may be mountain gods living in the mountains.

By Han Fei Home |

A stone wall on the Blackfish River, columnar joint is a geological name?

By Pig Bean 1➕ |

If you are not traveling by car, you don’t know how to get to this attraction, although the volcanic geological park ticket is included.

By Free Foshan Plum |

The Yajule real estate project has been built on the upper part of the joint column, and the Heiyu River is at the bottom.

By Picking mallow |

Even if you don't understand the geological composition and landform structure, anyone who looks up here will be attracted by the scene in front of them.

Countless basalt rocks are spread out in an orderly manner, though scattered in all directions, standing tall as if they were cast into the mountain by nature.

This type of columnar joint is rare not only in Tengchong, but also in the whole country.

When the magma flowed, was it affected or controlled by the topography of the time, creating the scene we see today? Today, the mottled basalt is silent, and a clump of wild grass grows tenaciously through its surface.

When the heroic song of ice and fire was cast into itself, the answer was also solidified within it, waiting for us, the people of later generations, to understand and decipher.

One thing is certain: without the Longchuan River fault that fractured the rock layers, and without the constant erosion and cleansing of the water, we wouldn't be able to see this amazing sight today. Every change in nature brings endless pain, but it also creates extraordinary miracles.

They bid farewell to the stars and greet the sunrise, standing forever silent above the vast earth and beneath the boundless sky. Alone, they bid farewell to history and greet the future, facing the ebb and flow of the tide and the coming and going of people.

By Nanhong Xianguan 137906 |

Columnar joints are a unique landform in volcanic areas. The hillside is covered with large screen-like, angular stone pillars.

By Pan D |

After crossing the suspension bridge, we arrived at the base of the columnar joints, near a water station and a settlement of several indigenous families. Standing below the columnar joints, while lacking the densely packed textures, the view was even more striking. However, those of us who weren't interested in geography still found it less interesting. On our way there, we happened to meet tourists descending the mountain from the columnar joint viewing platform. Upon asking, we learned there was a shortcut, so on our way back, we climbed directly from the viewing platform.

By -My Own Commoner- |

You can take a look at it from the mountain on the way. It is not recommended to go in again after entering the Blackfish River. It is a long way and you have to climb stairs. It doesn’t seem worth the effort because there is not much scenery to see along the way.

By Zhong Xiaobao |

Not a recommended place to go. There is nothing to see when passing by the Blackfish River.

By I'm not an editor |

After leaving the park, the bus took us for a while and we came to a place called "columnar joints". This phenomenon was quite strange. After some investigation, we found out that the cause was still related to volcanoes. Several groups of joints in different directions cut the rock into polygonal columns, and the columns were perpendicular to the base surface of the volcanic rock. Columnar joint structure is a primary tensile fracture structure with regular or irregular columnar shape commonly found in volcanic lava. It is more common in basalt, and sometimes in intermediate-acidic lava, ignimbrite, subvolcanic rock, and basic dykes. The author vaguely remembers that there used to be a place with similar columnar joints in a corner of Yellowstone National Park in the United States, and that place is also world-famous for volcanoes and geothermal energy.

By Gradually walking away and gradually losing books |

It is watched from an observation deck. The best viewing spot on the observation deck is equipped with a telescope. You can watch it for a fee.

By Alone with the wind |

Columnar joints are a relatively rare and unique geological surface phenomenon. Baoshan's columnar joints are found along the way from Tengchong's Volcanic Geopark to the Heiyu River Scenic Area.

It's important to note that the Tengchong Volcano Geological Park entrance fee includes three attractions: the volcano park itself, the columnar joints, and the Blackfish River. However, the latter two are quite far from the volcano park, more than a dozen kilometers away, and with no public transportation, you'll need to take a taxi or charter a car to get there.

By Zhang Xiaomao |

You have to go down countless steps and then come up again, which is like walking through a canyon. It is also very tiring. In fact, you can see the columnar joints without going down. You can see them from the small restaurant next to the parking lot. But it is still worth going down because you can see wild monkeys.

After going down to the canyon, there are columnar joints on the left and the Black Fish River on the right. There are many monkeys in the forest to the right. If you are lucky, you may encounter monkeys asking you for food on the road. We only saw them on the trees. Follow this road to the Black Fish River Scenic Area, which is 2 km away.

By Wang Xiaoxiao |

Another wonder of Tengchong Volcano Park is the magical and spectacular columnar joints, especially those distributed in the Heiyu River Canyon. They are truly a masterpiece of nature's magic and are worth seeing.

Columnar joints are columnar bodies formed after the magma that was ejected during a volcanic eruption and not exposed to the surface condensed. The various columnar joints in Tengchong are attributed to the Longchuan River fault that broke the rock layer and then exposed it under the scouring and cutting of the flowing water.

The total area of Tengchong's columnar joints is 2 square kilometers. They were formed about 40,000 years ago and are one of the largest, newest and best-preserved columnar joint groups discovered in my country so far.

By Insects |

The combined ticket includes access to Volcano Park, Columnar Joints, and Blackfish River. However, Columnar Joints and Blackfish River are a ways from Volcano Park, and the scenic area doesn't provide transportation, so you'll need to share a car. The Columnar Joints were under maintenance the day I visited, so I could only take a few photos from a distance.

By Extreme Wandering-Xiao Yang |

Columnar joints, affectionately called "divine pillars" by locals, are the largest, best-preserved, and youngest columnar joints discovered in my country to date. Columnar joints form when volcanic magma, at a temperature of 1200°C, crystallizes when it cools to 800-900°C. Because the magma contains hexagonal prisms of minerals such as plagioclase, olivine, hornblende, and pyroxene, these hexagonal prisms form upon cooling, forming what are known as columnar joints.

By As light as water |

On the banks of the Longchuan River in Tengchong County, Yunnan Province, stands a large columnar crystal formed by the condensation of magma that was ejected during a volcanic eruption and was not exposed to the surface. In geology, it is called "columnar joints", and the locals figuratively call it "Divine Pillar".

By inging |

It took 2 hours to walk back and forth from the Blackfish River and I only saw the side. Later, on the way to the Volcano Park, I didn't have to walk and could get a bird's eye view of the entire front columnar joint.

By Rongrong |

From a distance, it doesn't look very interesting, but the whole side of the mountain is made of similar rocks, which is quite different. I didn't expect it to be so big.

By 9 carats |

It is a wonder of the world, worth seeing and worth visiting.

By LHJ on the road |

This is the first time I have seen this kind of long, sectioned stone. It is said to be a unique landform here. It is quite novel.

By Enjoy Travel |

Near many volcanoes in Tengchong, the locals figuratively call them "divine pillars."

By Four |

This is columnar joints...

In a nutshell, don't expect too much from him.

By Rookie King |

The wonders of nature, marvel at the wonders of nature.

By Walking child |

It is a very famous geological landscape. I came here specifically to see it. It is really spectacular.

By Tracy Xiaoyun |

It is worth a visit for those who are interested in geography, but for ordinary tourists, it will be a bit boring.

By Late Evening |

After visiting the Volcano Park, we drove to the columnar joints. Located in Qushi Township, this "columnar joint" covers an area of about 2 square kilometers and was formed about 40,000 years ago. It is the largest, most complete, and youngest columnar joint discovered in my country to date.

By Everything is fine |

After getting off the hot air balloon, we headed to the next attraction in the Volcano Park: the columnar joints, which were formed when magma erupted and cooled. This is also one of the attractions in the Volcano Park, but it's very far from the park and difficult to reach without a car.

By freezing point |

This was formed when magma cooled after a volcanic eruption. It is said to be the largest columnar joint ever discovered.

By treedxcy |

The columnar joints and the Black Spring River are not very distinctive. I met a little green bird in the forest and was so scared that my hands were shaking.

By Lao Zhang |

The scenery was too ordinary and there was nothing to see, so I only took this one picture.

By Beautiful woman tasting tea |

The columnar joints are not interesting when viewed from a distance, so it is not recommended to visit this place.

By Car Leak_ZHANG |

It's included in the volcano scenic area ticket, and you need to charter a car from the volcano scenic area exit. The actual appearance is the same as the picture... It's a relatively typical geographical phenomenon, but not particularly beautiful...

But the Blackfish River, which is very close to this one, is not bad, so you can visit it by the way. Both spots are included in the volcano ticket.



According to locals, if you don't want to go to the volcano and want to see the columnar joints and the Blackfish River directly, you can eat at a nearby farm and the owner will be able to show you a free trail.

We bought tickets to see the volcano and then went there. Anyway, there was no one checking tickets at the entrance.

By Shadow follows |

In the Volcano Group Park, there is a natural wonder that cannot be seen anywhere else. This is the "columnar joints" formed by crystallization during the solidification process of volcanic lava. You can see the whole picture from a distance and the details can be seen up close.

By An elegant sugar ball |

The columnar joints can be seen from a distance on the mountain, but the locals suggested that we go down the mountain to see them up close. The columnar joints are a perfect work of nature "carved" by the cooperation of volcanic eruptions and river water. Afterwards, you can go to the Blackfish River.

By Three o'clock |

I took a panoramic photo of the columnar joints (columnar crystals formed by the condensation of magma that was ejected during a volcanic eruption and not exposed to the surface) in the farmyard in front of the columnar joint viewing platform. The driver said that it would be more spectacular when we walked to the foot of the mountain.

It takes about 30 minutes to walk from the viewing platform of the columnar joint to the entrance of the Blackfish River. Along the way, many local villagers set up various stalls. It looks very original.

By Son of the East |

The columnar joints are quite unique, like a cliff divided into several sections. One section looks like it's piled with firewood, while another section looks like someone has deliberately changed the direction of the rock's texture...

By Victory |

The columnar joints are a little far from the volcanic scenic area, but it's very close by car. Unfortunately, you are not allowed to walk under the rock wall now, so you can only watch it from a distance.

This is also a unique formation of the volcano. The driver said we were no longer allowed to approach, implying that driving down the mountain wouldn't be that useful. I don't know if this is true, but it didn't seem right to drag hungry people, young and old, over there just to take a few photos. So, we gave up.

By Yu Xinfly |

Coming out of the Volcano Geological Park, I passed by the columnar joints. The scenery was just average, but since I'd never seen them before, I felt like I'd learned something new. Seeing this phenomenon for the first time, I was amazed at the wonders of nature. I searched Baidu and learned that Tengchong has numerous volcanoes, and the columnar joints were formed by magma ejected from volcanic eruptions.

By The Adventures of Tintin |

It is a special geographical feature caused by the movement of the earth's crust. Due to time constraints, we only looked at it from a distance. If you have time, it is worth taking a closer look to see the wonders of nature.

By Simple |

It looks quite majestic from a distance and it should be said that it has certain geographical value, but its viewing value is average. However, this attraction is next to the Blackfish River and is free. You can go and see it. I think it is quite spectacular. Nature is really magical.

By Fairy Tale World |

There is no charge for the columnar joints. You can just stop by the roadside to see them. They are very spectacular. I personally think they are good. Friends who are interested in geography must see them. I have seen many netizens say that they are not very good before, so I didn’t have much interest in them. But when I saw them with my own eyes, I felt that they were very good.

By Qingcheng emei3 |

The geothermal Ken volcanic eruption remains, you can soak in the hot springs, a little more crowded.

By PMer |

The columnar joints are said to be formed by the cooling and solidification of magma as it flows downstream. It's a truly fascinating sight, reminiscent of the process of liquid metal cooling and crystallizing as it fills a mold during casting.

By Angry young people who don't want to grow up |

Columnar joints are columnar crystals formed by the condensation of magma that was ejected from a large volcanic eruption and is not exposed to the surface when it is ejected on the edge of a cliff. It is quite good.

By Ding Ding |

We came to the spectacular columnar joints, which are said to be formed by the rapid cooling and condensation of volcanic magma during flow. The observation deck did not give us a spectacular view, so we had to look up from the observation deck along the Blackfish River below, but it was too far to go down!

By Follow me everywhere |

Columnar joints are located in the Tengchong Volcanic Geothermal National Geopark in Tengchong County, Baoshan City, Yunnan Province. Columnar joints are a unique volcanic rock formation, formed by the condensation of magma that escaped during a volcanic eruption. They're worth a look, but getting there is quite inconvenient.

By Denny |

This is one of the two scenic spots in the volcanic scenic area - columnar joints. I don't think there is any need to go down~~ Just take a photo with your SLR from a distance~~

By Wenwen |

The columnar geological formations can be clearly seen from across a ravine, or you can walk up to the Blackfish River to see them. This is the largest, most complete, and youngest columnar joint discovered in my country to date.

By YH |

Well, I'm going to go back to the wonders of nature. Geology students might be more interested, but for the average person, the patterns on the mountains are actually quite pretty. Plus, with mountains, water, and trees, the scenery is quite nice.

By Pure sky and pure color |

After leaving the geological park, we went to see the columnar section. We just looked at the view from a distance. It was OK.

By Me after being struck by lightning |

We hurried to our next attraction—the columnar joints. Columnar joints are a volcanic phenomenon, with upright pillars arranged in neat rows. Since I was traveling with a tour group, I wasn't able to see them up close. I could only admire the wonders known as "divine pillars" from afar. From a distance, they appear flat, with no recognizable hexagonal prisms. Just a hint of texture is visible.

By Orange Smile |

It was not until I arrived in Tengchong that I learned that columnar joints are columnar crystals formed after the magma that was ejected during a volcanic eruption and not exposed to the surface condensed. I have to admire the magical power of nature.

By Little White Girl |

The master asked us to look at the viewpoint next to the small vendors... It's boring and I don't recommend going there.

By Little cat |

Columnar joints are also the product of volcanic eruptions. I have seen this thing many times. The one in the Northeast Wangtian'e Scenic Area is many times more spectacular than this one. Fortunately, this attraction does not require a ticket.

By A calm smile |

Tengchong's representative tourist spots,

Actually, there is nothing to see:

First, you can only watch from a distance.

Secondly, you need certain professional knowledge to understand this thing, otherwise you won’t understand it.

Third, there is nothing special about taking photos.



I also think the food sold near the columnar joints tastes good.

By Guess who I am |

Standing on the plank road, you can see that the mountains on both sides are steep and the rocks are in regular shapes. Some are arranged in layers in an arc shape, and some are arranged vertically, as if they were chopped with a knife or an axe. Nature is really magical!

By Little D's story |

Seeing this kind of landform for the first time, I was deeply impressed by the wonders of nature. It's hard to imagine that volcanic magma, flowing and solidifying, could carve such spectacular patterns on the towering cliffs. Columnar joints are one of my favorite attractions in Tengchong, perhaps because of their casual yet destined beauty, their uniqueness, or the surprise of their discreet location hidden among the mountains, waiting for your discovery. There are very few trees near the columnar joints, so be sure to wear sunscreen. There are quite a lot of mosquitoes near the water source, so remember to use mosquito repellent.

By xxm |

There is a small path on the right side of the gate, which leads to the columnar joints and the Blackfish River. After driving for about twenty minutes, we saw several viewing platforms on the side of the road, which are used to view the columnar joints on the opposite mountain. Columnar joints are columnar crystals formed after the magma that was ejected during a volcanic eruption and not exposed to the surface condensed. It was almost noon when we arrived there, and the sun was shining directly on our side. The opposite mountain was in the shade, so we could not see it very clearly.

By China-TravelNote users |

You can walk there from the Blackfish River Scenic Area, but it doesn't seem close. It seems quite popular because there is not only a small spot on the opposite side, but also the place where we are standing is more magnificent. You have to walk down to see it.

By Mom |

There is no scenery here, just standing on the observation deck and looking at the rocks on the opposite mountain, which are like pillars.

By xiaobai |

Only when you get down to the river can you truly see the stone pillars on the other side of the gorge wall, embedded directly into the mountain. They are truly amazing! They must have been created by the volcanic eruption. Geologists call them "columnar joints." This wonder is worth seeing!

By Big Fish |

"Columnar joints" are formed when lava flows out and cools after a volcanic eruption. They are all lined up, which is quite interesting.

By boo |

Look at the columnar joints, what a masterpiece of nature! They dazzled me!

By The soul is elsewhere |

The columnar joints can only be viewed from a distance. It takes a long detour to get to the bottom, and it is very difficult to climb back, so I can only look at it from a distance.

By Adian is me |

The columnar joints scattered throughout the Heiyu River Gorge in Qushi Township are truly a masterpiece of nature's craftsmanship. Travelers to Tengchong won't regret not seeing the Headless Mountain, but they will definitely regret not seeing the columnar joints!

By yellowann |

This place is only 10 minutes away from the Volcano Park. No tickets are required. You can see it from the viewing platform. You can also walk there from the Blackfish River Park, but it is more suitable to view it from a distance from the viewing platform.

By Wu Yanna |

On the contrary, the volcanic columnar joints (this area is over ten kilometers from the Volcano Geopark and is part of a package deal with the Blackfish River scenic area, connecting the three scenic areas. The guidebook says it's best to rent a car, as there probably aren't any public buses) were quite interesting. Although I saw volcanic columnar joints up close on the mountain walls at the Hong Kong Geopark last year, I was still surprised by the variety here. On the two mountain walls facing the river (supposedly, the river's erosion has exposed these columnar joints), the columnar joints are horizontal, vertical, and diagonal, resembling firewood and its stacks.

By Blue Lotus |

The distance from the Blackfish River to the columnar joints is quite suitable for walking. The scenery along the way is nice. The small bridges and flowing water are very suitable for taking pictures. The fresh air in the mountains is refreshing.

By Walking in Jiangnan |

After lunch, we started walking to the columnar joints. I couldn’t help but marvel at the magical power of nature.

By All the way west |

Looking out from the river (this word is a bit odd here, as the valley is so small and narrow it lacks any imposing presence, barely more than fifty meters) at the columnar joints, you'll be surprised at first glance: it's just a tiny area! But it's still a natural volcanic feature, so it's acceptable. Following the stone path down into the valley, we'll get a closer look at the details of this volcanic wonder. At the bottom, we'll discover that the cliff we were standing on on the other side is also a columnar joint.

By YE |

I went there when the sun was shining brightly. It was so hot. I could only see the rows of columns and strong joints. It was a wonder of nature.

By Morning coffee |

How are columnar joints formed?

The temperature of the volcanic magma during eruption is 1200°C. When the magma cools to 800-900°C, it crystallizes and forms columnar joints. Because the magma contains hexagonal prisms of minerals such as plagioclase, olivine, hornblende, and pyroxene, the hexagonal prisms form after cooling.

It looks like a magical work of art.
