Rock fins up to about 1 foot (30 centimeters) tall dominate this stereo scene from the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity. The component images were taken during the 3,058th Martian day, or sol, of Opportunity's work on Mars (Aug. 23, 2012). This outcrop is within an area informally named "Matijevic Hill."

This stereo mosaic combines views from the left eye and right eye of the Pancam to appear three-dimensional when seen through blue-red glasses.

The view spans an area of terrain about 30 feet (9 meters) wide. Orbital investigation of the area has identified a possibility of clay minerals in this area of the Cape York segment of the western rim of Endeavour Crater.
