Rock Fins at Cape York

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 (August 23, 2012). 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.

The view combines exposures taken through Pancam filters centered on wavelengths of 753 nanometers (near infrared), 535 nanometers (green) and 432 nanometers (violet). It [the top image] is presented in approximate true color, the camera team's best estimate of what the scene would look like if humans were there and able to see it with their own eyes.
