Rock fins up to about 1 foot (30 centimeters) tall dominate this 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). The view spans an area of terrain about 30 feet (9 meters) wide. This outcrop is within an area informally named "Matijevic Hill."
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.
The view combines exposures taken through Pancam filters centered on wavelengths of 753 nanometers (near infrared), 535 nanometers (green) and 432 nanometers (violet). It is presented in false color to make some differences between materials easier to see.
