The Kolyma Mountains are a mountain range located in the northeastern part of Siberia, Russia. They stretch approximately 1,000 kilometers and are part of the larger Chukotka region. The mountains are characterized by rugged terrain, deep valleys, and numerous glaciers, making them a significant geographical feature in the area. These mountains are known for their harsh climate, with long, cold winters and short summers. The Kolyma River, which flows through the region, is one of the major rivers associated with the mountains. The area is also rich in natural resources, including gold and other minerals, contributing to its historical significance during the Soviet era.
