Columnar jointing of basalt in Marte Vallis, Mars. The image shows layers of solidified lava flows exposed on the rim of a 16-kilometer-diamter crater in the Marte Vallis region on Mars. This image from the High
Resolution Imaging Science Experiment HiRISE instrument aboard NASA’s Mars Reconnaissance
124:
Jointed columns occur around the entire circumference of the crater, indicating that the lava flows cover a huge area: at least 200 square kilometers (77 square miles). The widespread lava flows stacked on top of one another appear similar to the terrestrial flood basalts of the
Columbia River Basin

Washington, where instances of columnar jointing are common. It is likely that runny lava from a distant source formed layers of basalt in Marte Vallis, and they were uncovered when an asteroid punched through the Martian surface.
