IR view of lava flows

October 12, 2009
Located 1200 kilometers south of the giant shield volcano Arsia Mons, this infrared, IR, temperature image shows the flow margin of a young lava flow from Arsia that covers a much older flow. This young flow is 20 to 30 meters thick across most of its boundary edge. The large, unnamed crater at the bottom of the image is 12 kilometers across and has a depth of more than 700 meters.
