This mosaic of frames from the navigation camera on NASA's Mars Exploration Rover Opportunity gives a view to the northeast from the rover's position on its 1,687th Martian day, or sol (Oct. 22, 2008).

By that date, Opportunity had driven southwestward from Victoria Crater, beginning a long trek toward a larger crater, Endeavour.
