The cluster of rocks labeled a "Rock Garden" in this image is where NASA's Mars Exploration Rover Spirit became embedded in April 2009.
Spirit used its navigation camera to capture this view of the terrain toward the southeast from the location Spirit reached on the 1,870th Martian day, or sol, of the rover's mission on Mars (April 7, 2009).
The ground just left of the center of the image is where Spirit became embedded later in April. Wheels on the western side of the rover broke through the dark, crusty surface into bright, loose, sandy material that was not visible as the rover approached the site.
