This image is made from multiple observations by the Landsat 7 satellite in the year 2000. It uses a combination of infrared, near-infrared, and visible light to better distinguish between the park’s various rock types. Sand appears in shades of yellow and tan. Granite rocks appear brick red. Blue areas are likely salts. As the patchwork of colors suggests, the geology of Tassili n’Ajjer is complex.
