Big Rock - Sol 154

Caption NASA originale:"This image was taken by NASA's MER Spirit's Front Haz-Cam during Spirit's 154th Sol on June 9, 2004. The Columbia Hills appear against the horizon. Directly in front of the Rover is the highest of the hills, Husband Hill, approximately 90 mt (about 295 feet) tall. The rock in the foreground is larger than other surrounding rocks, approximately 35 cm (approx. 14") across, but was not an observation target for Spirit. The tread marks in front of the rock are not a trench, but simply evidence that the Rover passed by as it continued its journey toward the Columbia Hills".
