This view from the base of "Burns Cliff" in the inner wall of "Endurance Crater" combines several frames taken by Opportunity's navigation camera during the NASA rover's 280th martian day (Nov. 6, 2004). It is presented in a cylindrical projection with geometric seam correction. The cliff dominates the left and right portions of the image, while the central portion looks down into the crater. The "U" shape of this mosaic results from the rover's tilt of about 30 degrees on the sloped ground below the cliff. Rover wheel tracks in the left half of the image show some of the slippage the rover experienced in making its way to this point. The site from which this image was taken has been designated as Opportunity's Site 37.
