The striking surface textures observed in this THEMIS image taken south of the volcano Arsia Mons are from different erupted lava flows. Many flows extend for several kilometers and are observed to crosscut previous existing flows. The variable surface textures could result from older and younger lava flows, differences in the composition and vessicularity of magma, or different degrees of weathering.
