The feature informally named "Shoemaker Ridge" in the "Cape York" segment of the western rim of Endeavour Crater includes outcrops that are likely impact breccias. Impact breccias are a type of jumbled rock previously examined by NASA's Mars Exploration Rover Opportunity at the "Chester Lake" target on Cape York. The view looks northward toward the southern edge of Shoemaker Ridge.

This image combines exposures taken by Opportunity's Panoramic Camera (Pancam) through three different color filters during the 2,715th Martian day, or sol, of the rover's work on Mars (Sept. 13, 2011). It is presented in false color to emphasize differences among materials in the rock and soil. The filters used are centered on wavelengths of 753 nanometers (near infrared), 535 nanometers (green) and 412 nanometers (violet).

Most of Cape York is covered in densely packed basaltic sands with small embedded rock clasts. Outcrops are exposed particularly on the inboard, or southeast, side of the cape. The name Shoemaker Ridge pays tribute to one of the founding fathers of planetary geology, Eugene Shoemaker.
