The Chukchi Mountains are a mountain range located in the northeastern part of Siberia, Russia. They stretch approximately 1,000 kilometers (620 miles) and are primarily composed of rugged terrain, with peaks reaching heights of over 1,500 meters (4,900 feet). The mountains are part of the larger Chukchi Peninsula and are known for their harsh climate and unique ecosystems. These mountains are home to various wildlife, including reindeer and polar bears, and are significant for the indigenous Chukchi people, who have lived in the region for thousands of years. The area is also rich in natural resources, including minerals and fossil fuels, making it an important region for exploration and development.
