In the remote Yana Highlands of Siberia, a giant and ominous hole known as the “Gateway to Hell” is expanding at an alarming rate, with scientists attributing its rapid growth to the effects of climate change. Officially known as the Batagaika Crater, this massive depression has tripled in size over the past 30 years and now spans an area of 200 acres, reaching depths of 300 feet.
The Batagaika Crater, shaped like a stingray or a giant tadpole, began as a small, barely noticeable crack in the 1960s, only visible in declassified satellite imagery. However, as global temperatures rise and permafrost melts, the crater has expanded significantly, revealing one of the oldest permafrost layers on Earth.

The crater’s sheer size and rapid expansion have captured the attention of scientists worldwide. “You’re talking mostly about frozen dirt underground, which by definition you often can’t see unless it’s been exposed somehow, like in this mega slump,” said Roger Michaelides, a geophysicist at Washington University, in an interview with Business Insider. Michaelides emphasized the importance of studying the Batagaika Crater to understand similar permafrost features across the Arctic.
Accelerating Expansion and Environmental Impact
A study published earlier this year found that the crater’s growth is accelerating due to the ongoing melt of permafrost, which has nearly reached the bedrock beneath it. According to glaciologist Alexander Kizyakov, the crater’s volume increases by approximately 1 million cubic meters annually. This poses significant risks to the surrounding environment, particularly the nearby Batagay River, where increased erosion could lead to habitat destruction and alter the riverine ecosystem.
The expanding crater also threatens to release vast amounts of greenhouse gases, as previously frozen organic carbon thaws and enters the atmosphere. Scientists estimate that the Batagaika Crater currently releases between 4,000 to 5,000 tons of carbon each year a figure expected to rise as the permafrost continues to melt.
Local researchers have expressed concern about the potential impact on nearby communities. Nikita Tananaev, a researcher at the Melnikov Permafrost Institute in Yakutsk, warned that the crater’s continued expansion could lead to significant alterations in the local ecosystem. “This will lead to significant alterations to the riverine habitat, and the effect of sediment escaping the slump is even seen in the Yana River, the major river in the vicinity,” Tananaev noted.
As the Batagaika Crater continues to grow, it serves as a stark reminder of the profound and far-reaching impacts of climate change on the Earth’s fragile ecosystems. Scientists are closely monitoring the situation, hoping to learn more about the long-term effects of permafrost thaw and the potential consequences for the planet’s climate system.
