This mosaic is composed of 7 frames (651a08 through 651a14) acquired by the Viking I spacecraft and covers a region of exteremely well preserved lava flows on the martian surface. Photoclinometry was used to derive profiles across some of these flows in order to determine their shapes.   The area shown is centered near 32 North and 214 West, and the resolution is about 50 m/pixel in the original images.
