At the Amboy lava field in California, bright sand is being blown across the dark lava from adjacent dry streambeds. MOC image AB1-10905 is illuminated from the left. The Amboy lava flows and cinder cone volcano are illuminated from the lower right. The Amboy photographs were taken from an airplane and are from the U.S. Geological Survey. Wind has blown material from right to left in the MOC image, and from upper left toward lower right in the Amboy pictures.
North is up in all figures.
