Ukok glacier, Mountain glacier in Altai region, Russia.
The Ukok Glacier is an ice formation located in the high peaks of the Altai Mountains where Russia meets China and Mongolia. The surface displays typical alpine glacier features including crevasses, compacted snow, and exposed rock at its edges.
The glacier formed over thousands of years through the cold climate of the high mountain region. Since the early 2000s, the ice mass has noticeably shrunk, reflecting shifts in the region's climate patterns.
The glacier lies in territory with deep spiritual meaning for Altai peoples, where mountain peaks and ice fields are woven into their traditional worldview. Visitors can sense this connection to the land through stories shared by local communities.
Access requires specialized mountaineering gear and an experienced guide, since the terrain is steep and riddled with crevasses. The best season to visit is during warmer months when weather conditions are less extreme.
The glacier is part of the UNESCO World Heritage Site Golden Mountains of Altai and shelters snow leopards and argali mountain sheep. These rare species are specially adapted to survive in this extreme high-altitude ice landscape.
