Chukotka Mountains, Mountain range in Chukotka Autonomous Okrug, Russia
The Chukotka Mountains are a mountain range in the far northeast of Russia, stretching between Chaun Bay and the Bering Sea. The range is built from sandstone, shale, and volcanic rock, all stacked in layers that are clearly visible across the terrain.
The range took shape over many geological eras, with different rock layers deposited at different periods in Earth's history. Tectonic forces and volcanic activity gradually shaped the terrain into its current form over millions of years.
The Chukchi people have used the valleys between these peaks as seasonal grazing grounds for their reindeer herds for generations. Traces of this way of life, including old camp sites and worn paths, are still visible to attentive visitors today.
The area is remote and hard to reach, and conditions can be harsh throughout the year, particularly in the colder months. Anyone planning a visit should prepare thoroughly and allow plenty of time for travel and changing weather.
Sandstone, shale, and volcanic rock appear side by side within the same range, which points to very different conditions at the time each layer formed. This rare combination makes the range an unusually interesting subject for geologists.
