NASA's Mars Exploration Rover Opportunity recorded this stereo view of the summit of "Cape Tribulation," on the western rim of Endeavour Crater, on the day before the rover drove to the top. The scene appears three-dimensional when seen through blue-red glasses with the red lens on the left.

This crest is about 440 feet (about 135 meters) higher in elevation than the plain surrounding the crater, higher than any other point Opportunity has reached since it began exploring the Endeavour rim in 2011.

This view combines images taken by the left-eye and right-eye cameras of Opportunity's stereo navigation camera on Jan. 5, 2015, during the 3,893rd Martian day, or sol, of the rover's work on Mars. The summit is about 40 feet (about 12 meters) southwest of the location from which the images were taken.
