Valleys much younger than well-known ancient valley networks on Mars are evident near the informally named "Heart Lake" on Mars. This map presents color-coded topographical information overlaid onto a photo mosaic. Lower elevations are indicated with white and purple; higher elevations, yellow.

Landscape of Former Lakes and Streams on Northern Mars

Valleys younger than better-known ancient valley networks on Mars are evident on the landscape in the northern Arabia Terra region of Mars, 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 (northwest).

Data from the Mars Orbiter Laser Altimeter (MOLA) on 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 the Thermal Emission Imaging System (THEMIS) camera on NASA's Mars Odyssey orbiter, covering an area about 120 miles (about 190 kilometers) wide. The mapped area is centered near 35.91 degrees north latitude, 1 degree east longitude on Mars.

These lakes and streams -- also shown on a hydrologic modeling map at -- held water several hundred million years after better-known ancient lake environments on Mars, according to 2016 findings.

MOLA was built and operated by a team headed at NASA Goddard Space Flight Center, Greenbelt, Maryland. THEMIS was built and is operated by a team headed at Arizona State University, Tempe. NASA's Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, managed the Mars Global Surveyor Project and manages the Mars Odyssey Project for NASA's Science Mission Directorate, Washington.
