The story of Altai Mars
Millions of years ago this valley was the floor of an ancient lake. Minerals in the clay, rich in iron and other elements, now colour the eroded hills in bands of red, ochre and white.
Locals call the valley Kyzyl-Chin, meaning "red wall". Travellers nicknamed it "Altai Mars" for its unearthly look. A smaller "Mars 2" valley lies nearby.
