Altai Mountains

The Altai Mountains are a major mountain range in Central Asia, where the countries of Russia, China, Mongolia, and Kazakhstan come together. This area is where important rivers like the Irtysh and Ob begin their journeys. The tallest peak in the Altai Mountains is Belukha, which rises to about 4,506 meters (14,783 feet) above sea level.

The Altai Mountains connect to the Sayan Mountains in the northeast and become lower toward the southeast, blending into the high plains of the Gobi Desert. In the southwest, they are separated from the even taller Tian Shan mountains by the Junggar Basin.

People living in the Altai region are few but come from many different backgrounds, including Turkic peoples, Mongols, and Volga Germans. Many are semi-nomadic and depend on raising animals like cattle, sheep, and horses, as well as hunting, farming, cutting trees, and mining for their living. The idea of an Altaic language family gets its name from these mountains.

Etymology and modern names

The name "Altai" comes from a word meaning "gold" in ancient Turkic languages. This idea of gold connects to similar words in many nearby languages.

People living near the Altai Mountains call them different names depending on their language. In Mongolian, they are called Altain nuruu. In the Altay language, they are known as Altay tuular. In Kazakh, they are called Altaı taýlary. In Russian, they are referred to as Altajskije gory. In Chinese, the mountains are named ā'ěrtài shānmài, and in Uyghur, they are called Altay Taghliri. Each of these names shows how different cultures see and name this important mountain range.

Geography

For the area north of the Altai, see Geography of South-Central Siberia and South Siberian Mountains.

The Altai Mountains are a vast, remote mountain system in Central Asia, covering an area of 845,000 km². They stretch for 2,525 km from northwest to southeast. The region includes the Sailughem Mountains, also known as Kolyvan Altai, which run northeast and merge with the Sayan Mountains.

The area is home to many lakes, such as Uvs, Khyargas, Dorgon, and Khar, and several mountain ranges including the Tannu-Ola Mountains and Khan Khökhii mountains. The highest peak in the range is Belukha Mountain, reaching 4,506 m above sea level, with another peak close behind at 4,400 m. These peaks feed several glaciers and create stunning landscapes.

Fauna

The Altai mountains are home to many different animals because of their varied landscapes, including grassy areas, forests, and high-altitude plants. Steep slopes are where you can find the Siberian ibex, while gentler slopes host the rare argali. Five types of deer live here, such as the Altai wapiti and the Siberian roe deer. Large predators like snow leopards, wolves, Eurasian lynx, and brown bears also roam these mountains.

In the past, the Caspian tiger lived in the southern parts of the Altai mountains, but today it is no longer found there. The wisent, a type of ancient cattle, once lived here too, and now there is a small group kept safe in the Altai Republic. Moor frogs can be seen near water up to 2,000 meters high in the mountains.

History

The Altai Mountains have had a stable climate since the last ice age, and many animals from that time still live there. Scientists discovered a group of ancient humans called the Denisovans here. Their remains and tools were found in Denisova Cave, showing that they lived alongside Neanderthals and early humans.

Later, people known as the Afanasievans lived in the area and were among the first herders in East Asia. Many important ancient groups, like the Xiongnu and the First Turkic Khaganate, ruled the region. Some believe that skiing may have started in the Altai Mountains, based on ancient rock drawings found there.

World Heritage Site

Main article: Golden Mountains of Altai

A large area of 16,178 km² (6,246 sq mi)², including the Altai and Katun Natural Reserves, Lake Teletskoye, Mount Belukha, and the Ukok Plateau, is recognized as a World Heritage Site called the Golden Mountains of Altai. This area shows a full range of plant life from steppe to alpine vegetation. It is also important for protecting rare animals like the Snow leopard, Altai argali, and Siberian ibex. The nearby Uvs Nuur basin is also protected.

Geology

The Altai Mountains are shaped by the movement of Earth's plates, where the land pushed up to form these tall peaks. The area has many cracks or faults in the ground, like the Kurai fault zone and the Tashanta fault zone. These faults help scientists understand how the mountains were made.

Scientists have found signs of huge floods in the past in this region. These floods came from giant lakes formed by glaciers, much bigger than what was previously believed to be the largest ice dammed lake in the world.

Seismic activity

Although earthquakes don't happen often in the Altai Mountains, a big one struck on September 27, 2003. This earthquake caused damage and changed life for people living nearby.
