Curiosity rover used one of its Mast Camera to capture this last look at a section of the field of bright white sulfur stones before leaving Gediz Vallis channel. The field was where the rover made the first discovery of pure sulfur on Mars by driving over a rock and cracking it open to reveal the yellow crystals inside. Scientists are still unsure exactly why these pure sulfur rocks formed here. This composite is made up of several overlapping images captured on October 11, 2024 (Sol 4331).
