Lava Flows on Ascraeus Mons, Mars

Mars
This image was taken near the summit of the giant Tharsis shield volcano Ascraeus Mons. The crater at right is about 600 m in diameter and appears to be an impact crater. A sinuous rille, a channel formed by subsurface lava flows, runs across the top of the image. The rough surface at the bottom of the image may have been formed by an aa lava flow, while the upper part of the image represents smoother pahoehoe lava. The image is centered at 11.5 N, 103.5 W.
