This panorama taken by NASA's Mars Exploration Rover Opportunity includes an outcrop informally called "Cambridge Bay." Opportunity examined this outcrop in August 2010. The outcrop includes an apparent contact between two bedrock units which have different textures and perhaps compositions.
Opportunity used its navigation camera during the 2,335th Martian day, or sol, of the rover's mission on Mars (Aug. 18, 2010) to take these images. Science instruments on the robotic arm were used to measure the chemistry and texture of the outcrop from Sol 2340 (Aug. 24, 2010) to Sol 2346 (Aug. 30, 2010). Opportunity has since resumed its journey toward the long-term destination of Endeavour Crater. Portions of Endeavour Crater's rim are visible on the horizon.
