The European Space Agency’s Mars Express spacecraft took this image of Claritas Fossae, a series of linear fractures located in the Tharsis region of Mars. It’s located on the Tharsis rise, which is south of the three large volcanoes known as the Tharsis Montes. It has linear fractures up to 150 km (93 miles) across, which were created when the whole Tharsis region bulged up several kilometres. The smooth surfaces are places where the area was covered by lava flows.
