Altai Mountains

The Altai Mountains are a grand mountain range in Central Asia, where four countries meet: Russia, China, Mongolia, and Kazakhstan. These towering peaks are where important rivers like the Irtysh and Ob begin their journey. The highest point in the Altai Mountains is Belukha, standing tall at 4,506 meters (about 14,783 feet) above sea level.

The Altai Mountains connect to other ranges, such as the Sayan Mountains to the northeast, and gradually slope down toward the Gobi Desert in the southeast. To the southwest, they are separated from the even higher Tian Shan mountains by the Junggar Basin.

People living in this area are few but come from many different backgrounds, including Turkic peoples, Mongols, and others. Their lives depend on raising animals like cattle, sheep, and horses, as well as hunting, farming, working in forests, and mining. The name of a group of languages once thought to be related, called the Altaic language family, comes from these famous mountains.

Etymology and modern names

The name "Altai" comes from an old word meaning "gold" or "golden." This idea of gold connects to the rich history and culture of the area.

People in different countries and languages have their own special names for these mountains. In Mongolia, they are called Altain nuruu, in the Altay language they are Altay tuular, in Kazakhstan they are Altaı taýlary, in Russia they are Altajskije gory, in Uyghur they are Altay Taghliri, in Chinese they are ā'ěrtài shānmài, and in Dungan they are Arteː shanmeː. Each name shows how important these mountains are to the cultures around them.

Geography

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

The Altai Mountains are a large, remote mountain system in central Asia covering about 845,000 km² (326,000 sq mi). They stretch about 2,525 km (1,569 mi) from northwest to southeast. The highest peak is Belukha Mountain, which reaches 4,506 m (14,783 ft) above sea level.

The mountains include several smaller ranges and many lakes. One famous lake is Teletskoye, which is about 80 km long and 5 km wide. The Altai Mountains are home to people such as the Telengit and Kyrgyz, who live in the valleys and plateaus.

Fauna

The Altai mountains are home to many different animals because of their varied landscapes, including grassy areas, forests, and high alpine regions. Steep slopes are where you can find the Siberian ibex, while gentler slopes host the rare argali. There are five kinds of deer, such as the Altai wapiti and Siberian roe deer. Large animals like wild boars live in lower areas, and predators such as snow leopards, wolves, Eurasian lynx, and brown bears roam the northern parts. Birds like the western Siberian eagle-owl also make their home here.

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 cow, used to live in the Altai mountains until the Middle Ages, and now there is a small group kept safe in the Altai Republic. Small frogs known as moor frogs live near water, even at very high altitudes.

History

The Altai Mountains have had a stable climate for thousands of years, which helped preserve many ancient remains. Scientists discovered a group of early humans called the Denisovan here, living alongside other ancient humans like Neanderthals and early Homo sapiens. Their discovery came from DNA and tools found in the Denisova Cave.

Over time, many different groups lived in the Altai Mountains, including early herders and horse riders. Some believe the mountains might be where people first began to ski, 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 a special place protected by the world called a World Heritage Site. It is named the Golden Mountains of Altai. This area shows many different kinds of plants, from grassy lands to forests and snowy mountains. These mountains are also important for protecting animals that are in danger, like the Snow leopard, Altai argali, and Siberian ibex. Nearby, the Uvs Nuur basin is also protected.

Geology

The Altai Mountains are shaped by the movement of Earth's plates, where the land of India pushed into Asia long ago. This created cracks and faults in the ground, like the Kurai and Tashanta fault zones. These areas can still shift and cause changes in the land.

Scientists have found signs of huge floods in the past in this region. These floods came from a very large lake formed by glaciers, even bigger than a famous lake that once held back ice in North America.

Seismic activity

Earthquakes don’t happen often here, but in 2003, a strong one shook the area near the Chuya Basin. This quake caused damage and changed life for people living nearby.
