Altai Mountains

• 1. Introduction

  ›

  The Altai Mountains sit at the point where Russia, China, Mongolia, and Kazakhstan all meet, a convergence zone that has drawn humans, animals, and entire civilizations for tens of thousands of years. At the heart of the range stands Belukha, a double-headed peak whose twin summits reach 4,506 m and 4,400 m respectively. From that summit, glaciers spill down into valleys that eventually feed the Irtysh and the Ob, two of Asia's great rivers. The name Altai itself traces to an ancient Turkic root meaning "gold" or "golden," a word preserved in Old Turkic as altun. What drove so many cultures to name this place after gold, and what did the mountains actually offer the people who lived among them? The answers reach from an ice age cave where three species of early human coexisted, to a Bronze Age migration that reshaped the populations of Europe and Asia, to a UNESCO-listed wilderness where snow leopards still patrol ridgelines above the clouds.

• 2. A Landscape of Extremes

  ›

  The Altai system covers an area of 845,000 square kilometers and stretches 2,525 km from northwest to southeast. Within that enormous sweep, the terrain shifts from steppe to taiga to high alpine plateau in ways that geographers find almost improbably complete. Lake Teletskoye, tucked into the range's interior, measures 80 km long and just 5 km wide, yet plunges to a maximum depth of 310 m with a mean depth of 200 m. Its shores rise almost sheer to over 1,800 m, turning it into something closer to a fjord than a typical mountain lake.

  The Sailughem Mountains, also known as the Kolyvan Altai, anchor the northern part of the system. Snow cover on their slopes begins at 2,000 m on the north-facing side and 2,400 m on the south-facing side. Mountain passes across the Sailughem are rare and punishing; the Chapchan-daban sits at 3,217 m and the Ulan-daban at 2,827 m. East and southeast, the range drops off gradually through a series of minor plateaus, including Ukok at 2,380 m, Chuya at 1,830 m, and Kendykty at 2,500 m, before finally merging into the high plateau of the Gobi Desert.

  The range does not end cleanly at any border. In the northeast it merges with the Sayan Mountains. In the southwest, the Junggar Basin separates it from the higher Tian Shan range. The Ek-tagh, or Mongolian Altai, rises as a steep escarpment from the Dzungarian depression on its southern side while descending more gradually northward to the Mongolian plateau. East of 94 degrees East longitude, the system continues as a double series of lower, less sharply defined chains that gradually fade into the surrounding landscape.

  The Katun River traces one of the range's most dramatic internal journeys. It begins as a gorge on the southwest slope of Belukha, bends sharply, pierces the Katun Belki range, and emerges into a wider valley before joining the Biya River at Biysk. The Katun Belki themselves average about 3,000 m in elevation and are mostly snow-clad. At their confluence with the Biya, the two rivers form the Ob, which carries the meltwater of the Altai westward across Siberia toward the Arctic Ocean.

• 3. The Cave at Denisova

  ›

  Denisova Cave, in the Altai mountains of southern Siberia, has yielded evidence that three separate branches of the human family once shared the same location. Neanderthals, anatomically modern Homo sapiens, and a third lineage now known as Denisovans have all left traces there, making it the only known place in the world where all three hominids are confirmed to have lived. The Denisova hominin was dated to approximately 40,000 years ago and was first identified in 2008.

  What makes Denisova Cave unusual is that knowledge of the Denisovans comes almost entirely from DNA evidence and artifacts rather than skeletal remains. No complete skeletons have been recovered. The cold and stable temperatures inside the caves have preserved ancient DNA in a condition rarely seen elsewhere, allowing researchers to extract and sequence genetic material that would otherwise have degraded completely.

  The Altai Mountains retain a climatic stability that stretches even further back in time. The range has changed little since the last ice age, and most of the mammal species present then are still present today, with exceptions such as the woolly mammoth. This continuity made the region a kind of living archive, one that preserves both genetic material and cultural artifacts across timescales that elsewhere have been wiped clean by climate shifts or human development. A dog-like canid found in the Razboinichya Cave and dated to 33,000 years ago was confirmed by DNA analysis published in 2013 to be more closely related to modern dogs than to wolves, pushing back the timeline for early domestic canids in the region.

  Eastern Scythian burials discovered in the Altai have yielded something rarer still: soft tissue. Skin and hair have been preserved in an excellent state, offering a level of physical detail from the ancient world that is almost without parallel.

• 4. Migrations and Empires

  ›

  Around 3700-3300 BCE, a population descended from the pre-Yamnaya Repin culture of the Don-Volga region moved across the Eurasian Steppe and arrived in the Altai Mountains. These were the Afanasievans, considered the earliest herders of East Asia and credited with establishing the long tradition of pastoralism that would define life across Mongolia for millennia. For a period, they appear to have coexisted in the Altai region with the early Chemurchek culture before being replaced during the late Bronze Age and early Iron Age by a second wave of Indo-European migrations from the Andronovo culture.

  The Altai has also been identified as the likely point of origin for a phenomenon archaeologists call the Seima-Turbino Phenomenon. It arose during the Bronze Age, around the start of the 2nd millennium BC, and triggered a rapid and massive migration of peoples outward from the region into distant parts of Europe and Asia. The scale and speed of that dispersal have made it one of the more studied puzzles of prehistoric demography.

  In subsequent centuries the area passed through successive political structures: the Xiongnu Empire, the First Turkic Khaganate, the Uyghur Empire, and the Yeniseian Kyrgyzs. During these periods the local population became fully Turkicized, both culturally and linguistically. Historians note increasing evidence for a partial continuity running from the eastern Scythians to the Turkic-speaking peoples of the Altai region, suggesting these layers of political change did not entirely erase earlier populations.

  Much later, in the 18th century, the Bukhtarma Valley became a refuge for a very different kind of migrant. Runaway Russian peasants, serfs, and religious schismatics known as Raskolniks settled the valley's middle and lower sections and created a free republic on what was then Chinese territory. After Russia annexed the area in 1869, colonization of those same valleys proceeded rapidly.

• 5. Wildlife and the Snows

  ›

  Snow leopards still move through the Altai, sharing high terrain with the Siberian ibex on steep slopes and the rare argali on gentler ground. The argali, the world's largest wild sheep, is among the species cited by UNESCO when it designated the Golden Mountains of Altai as a World Heritage Site. The total protected area runs to 16,178 square kilometers and incorporates the Altai and Katun Natural Reserves, Lake Teletskoye, Mount Belukha, and the Ukok Plateau.

  Five species of deer inhabit the range, ranging from the Altai wapiti to the moose and the forest reindeer, though moose and reindeer are restricted to the northern parts. Wolves, Eurasian lynx, and brown bears share the landscape, while wolverines appear in the northern sections. The Tien Shan dhole, a northwestern subspecies of the Asiatic wild dog, also lived in the region. Moor frogs are found near water sources at elevations as high as 2,000 m.

  Until the 20th century, the Caspian tiger ranged as far north as the southern Altai, reaching Lake Zaisan and the Black Irtysh. Individual animals were shot as far north as the area around Barnaul. The closely related Amur tiger carries the scientific name Panthera tigris altaica, a direct reference to the mountains. The wisent, Europe's largest land animal, was present in the Altai until the Middle Ages and possibly as late as the 18th century; a small herd now lives in a nursery within the Altai Republic.

  The protections afforded by UNESCO have not gone unchallenged. Alleged violations involving the Altai argali sheep and other species, combined with accusations of corruption, became the center of what was called the Altaigate Scandal. The incident followed the death of several Russian VIPs in a helicopter crash early in 2009, reportedly during a poaching excursion.

• 6. Skiing, Geology, and Deep Water

  ›

  Cave petroglyphs within the Altai Mountains in modern China show human figures on skis chasing an ibex. A study published by the Australian Rock Art Research Association in 2016 estimated this rock art to be between 4,000 and 5,250 years old, which would make it at least as old as ancient skiing evidence from Scandinavia and possibly older. Dating petroglyphs precisely with current technology remains difficult, but the Altai's claim to the origins of skiing gains textual support from the oldest known written description of skiing, found in a Chinese text from the Western Han Dynasty, dated between 206 BC and 24 AD, which refers specifically to skiers in the Altai Mountains.

  Below the snowfields, the geology is equally active. The Siberian Altai represents the northernmost region affected by the tectonic collision of the Indian subcontinent into Asia. Fault systems running through the area include the Kurai fault zone and the more recently identified Tashanta fault zone. These are typically thrusts or right-lateral strike-slip faults, several of which remain tectonically active. Geologist Victor R. Baker discovered evidence of past cataclysmic floods in the Altai Mountains of Siberia, originating from a glacial lake even larger than Lake Missoula, which was once considered the world's largest ice-dammed lake.

  On the 27th of September 2003, the region's active tectonics produced a magnitude 7.3 earthquake centered in the Chuya Basin. The quake and its aftershocks caused $10.6 million in damage according to the USGS and wiped out the village of Beltir entirely. The Altai-Sayan ecoregion, straddling the intersection of Central Asian and Siberian faunal zones, continues to absorb the slow collision of the tectonic plates beneath it, a process that has shaped every valley, fault, and ridgeline in the range.
