Ecology

The country through which it passes is thinly populated, and is dominated by tundra, with a rich variety of plant life. Much of the region's landscapes are dominated by rugged mountains. For nine months of the year the ground is covered with snow, and the frozen rivers become navigable roads. George Kennan, an American working on the Western Union Telegraph Expedition in the late 1860s, found that dog sled travel on the lower Anadyr was limited by lack of firewood.
