During the most recent Marian winter, NASA's Mars Exploration Rover Opportunity was stationary for four months -- and took 817 images of the surrounding terrain, which were stiched together to create the above panorama (of which you can see a high-resolution version here). The site is near the northern tip of the "Cape York" segment of the western rim of Endeavour Crater.
The panorama combines exposures taken through Pancam filters centered on wavelengths of 753 nanometers (near infrared), 535 nanometers (green) and 432 nanometers (violet). The view is presented in false color to make some differences between materials easier to see.
