Heiyoushan Black Oil Mountain Guide | Karamay Natural Asphalt Mounds

A short drive northeast of Karamay city center, the ground turns black, viscous, and alive. Black Oil Mountain — Heiyoushan in Chinese — is a rare natural phenomenon where crude oil seeps from the earth’s crust and has been doing so for millions of years. Unlike typical mountains formed by tectonic forces, these low, dark mounds are the result of petroleum migrating upward, leaving behind heavy bitumen that mixed with sand and soil.

The site is not only a geological curiosity but also the symbolic birthplace of Karamay’s oil industry, marking the spot that led to the discovery of one of China’s largest oilfields in 1955. For travelers driving the Silk Road or exploring the oil country of northern Xinjiang, Black Oil Mountain offers a brief, surreal stop that connects the region’s deep natural history with its modern industrial identity.

Geology and Formation of Heiyoushan

How Crude Oil Becomes a Mountain

The process that created Black Oil Mountain is straightforward yet spectacular. Deep underground, crude oil under pressure finds a path to the surface through fractures in the rock layers. At Heiyoushan, that seepage has been continuous for roughly one hundred million years. As the oil reaches the air, lighter hydrocarbons evaporate, leaving behind heavy asphalt and bitumen.

Over millennia, this sticky residue accumulated into mounds that now rise several meters above the surrounding desert plain. The ongoing activity means visitors can see raw oil bubbling up in small pools, sometimes with gas bubbles popping on the surface. The ground underfoot is dark, soft, and occasionally sticky — a literal oil seep in action.

Relationship to the Karamay Oilfield

Heiyoushan is not just a random seep; it is a surface expression of the same petroleum system that feeds the vast Karamay oilfield. The site is often called the “Mother of Karamay” because it revealed the oil-bearing potential of the region long before modern exploration. In the 1950s, geologists recognized that the continuous seepage indicated a large reservoir below.

The discovery of Well No. 1 in 1955, less than 2 kilometers from the mounds, confirmed the field, leading to the rapid development of Karamay as China’s first major oil-producing city after the founding of the People’s Republic.

Historical Significance: The Origin of China’s Oil City

The Kyrgyz Nomad and the First Discovery

Local legend credits a Kyrgyz herdsman with the first practical use of the seep. According to the source data, he noticed the thick oil could lubricate cart axles, a solution in a remote desert where no other lubricant was available. While the story may be folklore, it underscores how the surface oil was visible and usable long before industrial extraction began.

The Breakthrough of Karamay No. 1 Well

The pivotal moment came on October 29, 1955, when the drilling of Karamay No. 1 Well struck oil. That well, located near Heiyoushan, was the first successful oil well in China after 1949.

It transformed a barren, uninhabited desert into the foundation of a new industry. Today, a commemorative monument built in 1982 stands at Heiyoushan, marking the site’s role as the origin point of the Karamay oilfield. The monument and the walking trails around it allow visitors to appreciate both the natural wonder and the historical milestone.

Visitor Experience at Black Oil Mountain

What to Expect: Walking Trails and Bubbling Oil

Heiyoushan is a compact site, easily accessible from Karamay. A network of wooden boardwalks leads across the mounds, protecting both visitors and the delicate oil-soaked surface. Along the paths, you can observe dark, viscous oil seeping from the ground, sometimes forming small pools.

The smell of crude oil is present — it is not overpowering, but distinctive. The bubbling appearance of natural gas rising through the oil adds to the surreal atmosphere. The highest point of the mounds offers a view of the surrounding plain, dotted with the nodding pumpjacks of the working oilfield and the towers of modern Karamay beyond.

The Contrast of Nature and Industry

One of the most photographed scenes at Heiyoushan is the juxtaposition of the ancient, black mounds with the steel and concrete of the city skyline. The nodding donkeys — pumpjacks that rhythmically extract oil from the ground — seem to echo the natural seepage that still occurs at the site. This visual metaphor of nature supplying the resource and human ingenuity harnessing it is powerful and unique.

Photography Tips

• Best light: Early morning or late afternoon when the low sun accentuates the texture of the oily surface.
• Contrast shots: Include the nodding pumpjacks or the Karamay skyline in the background to emphasize the industrial context.
• Macro details: Close-up shots of the bubbling oil or the mixing of bitumen with sand and small rocks.
• Watch your gear: The oil can be sticky; keep camera bags off the ground. Use a polarizing filter to reduce glare on wet oil surfaces.

Practical Travel Information

Location and Getting There

Black Oil Mountain is located approximately 2 kilometers northeast of Karamay city center. From downtown, a short taxi ride or self-drive will get you there in under 10 minutes. The site is well signposted in Chinese, but international visitors may find it easier to use a map app or ask the hotel concierge to write the name (黑油山) for the driver. There is no public transit directly to the site, so arrange a private car or taxi.

Best Time to Visit

The recommended seasons are summer (June to August) and autumn (September to October). Summers are hot but dry, and the oil is more fluid, making the bubbling activity more visible. Autumn offers milder temperatures and clear skies for photography. Winter is cold and windy; spring can bring dust storms. Avoid visiting in the middle of the day during peak summer if you are sensitive to heat, as there is little shade.

Altitude and Climate

The elevation at Heiyoushan is recorded as 420 meters above sea level, though some sources mention 800 meters (unconfirmed). In either case, altitude is not a concern — the site is effectively at low elevation. The climate is arid, typical of the Dzungarian Basin. Carry water, sunscreen, and a hat, especially if walking the trails for more than 30 minutes.

Ticket and Opening Hours

According to the source data, entry to Heiyoushan is free. However, this has not been verified against official sources. Hours of operation are not provided in the source data; as an open-air site, it is likely accessible during daylight hours, but confirm locally. The monument and walking trails are outdoors, subject to Xinjiang’s weather conditions.

Who Should Visit and Who Might Skip

Ideal for:

• Geologists and petroleum industry enthusiasts
• History buffs interested in China’s industrial development
• Travelers on a Karamay or Silk Road road trip looking for a quick, unique stop
• Photographers seeking unusual landscapes

Not ideal for:

• Visitors expecting a traditional mountain with hiking trails (the mounds are low, only a few meters high)
• Those sensitive to petroleum odors (the smell is noticeable but not overwhelming)
• Families with very young children (surfaces can be sticky and uneven)

Safety and Precautions

• Sticky ground: The oil can adhere to shoes. Wear old sneakers or boots that you don’t mind getting dirty. Avoid sandals or open-toed shoes.
• No swimming or touching: Do not touch the oil pools directly. The crude may contain irritants. Stick to the boardwalks.
• Fire hazard: No smoking or open flames near the seeps, as natural gas is present.
• Weather: In summer, the exposed site offers no shade; bring sun protection. In winter, wind chill can be severe.
• Parking: There is a small parking area near the entrance, but facilities are basic.

Nearby Attractions in Karamay

No official duration is given. Most visitors spend 20 to 40 minutes walking the boardwalks and taking photos. It is a short stop rather than a half-day excursion.

Are there walking paths?
Yes, the site features wooden boardwalks and a commemorative monument built in 1982. The paths are easy to walk and well-maintained.

Is the oil still active?
Yes, the source data confirms that crude oil continues to seep and bubble with natural gas. The process is ongoing.

Do I need a guide?
Not necessarily. The site is small and self-explanatory with the monument and signs (mostly in Chinese). However, a local guide can provide context about the oil history.

Final Thoughts

Black Oil Mountain is a testament to the power of slow geological processes and the way surface clues can unlock vast underground resources. For travelers passing through Karamay, it offers a brief but striking detour — a chance to stand where the earth’s oil budget meets the sky.
