Valleys younger than better-known ancient valley networks on Mars are evident on the landscape in the northern Arabia Terra region, particularly in the area mapped here with color-coded topographical information overlaid onto a photo mosaic. The area includes a basin informally named ‘Heart Lake’ at upper left. Data from NASA’s Mars Global Surveyor orbiter are coded here as white and purple for lower elevations, yellow for higher elevation. The elevation information is combined with a mosaic of images from NASA’s Mars Odyssey orbiter, covering an area about 120 miles (about 190 km) wide. The mapped area is centered near 35.91 degrees north latitude, 1 degree east longitude on Mars. Image credit: NASA / JPL-Caltech / ASU.
