The "Columbia Hills" flank Spirit's path in this view. By studying the layered rock at Columbia Hills, scientists were able to tell a story of ancient water on Mars. Spirit has traveled above the plains since arriving at the "Columbia Hills" on sol 156 (June 11, 2004). It covered much of that distance driving on only five of its six wheels.
The images used to make this approximately false-color mosaic were taken with Spirit's panoramic camera on Sol 135.
