The D&M Pyramid (Original NASA/MGS/MSSS b/w Frame)

Caption NASA originale:"The mosaics shows a Cydonia landform popularly known as the "D&M Pyramid." It is located near 40.7°N, 9.6°W. Although it is not really shaped like a pyramid, the Cydonia landform is 1 of thousands of massifs, buttes, mesas, knobs and blocks that mark the transition from the far northwestern Arabia Terra cratered highlands down to the northeastern Acidalia Planitia lowlands. Each block, whether shaped like a face, a pyramid, or simply a mesa, massif or knob, is a remnant of the bedrock of northeastern Arabia that was left behind as erosion slowly degraded the terrain along this zone between the highlands and the lowlands. A few outcroppings of layers in this ancient bedrock can be seen in the mosaic of the pyramid-like landform shown here; much of the landform is covered with eroded mantling material that was deposited long after this highlands remnant became an isolated feature in Cydonia".
