Caption NASA:"How did these layers of red cliffs form on Mars? No one is sure. The Northern Ice Cap on Mars is nearly divided into two by a huge division named Chasma Boreale. No similar formation occurs on Earth. Pictured here, several dusty layers leading into this deep chasm are visible. Cliff faces, mostly facing left but still partly visible from above, appear dramatically reddish. The light areas are likely water ice. This image spans about 1 Km near the North of Mars, and the elevation drop from right to left is over one kilometer. One hypothesis relates the formation of Chasma Boreale to underlying volcanic activity".
