Defrosting the Crests of Inca City, LAT: -81.5° LONG: 296.3° “The nature of this polygonal network, unique on Mars, remains poorly understood, but seems to be linked to volcanic dykes covered by eolian sand. These terrains are close to the South pole and undergo springtime defrosting in dark patches that become progressively larger as temperatures climb,” writes geophysicist Nicolas Mangold in This is Mars.
