Laguna Hollow: Panorama (1) - Sol 44 (b/w - elab. NASA)

Caption NASA originale:"This image shows the shallow depression dubbed Laguna Hollow before the MER Spirit drove into it to sample its bed of fine sediments on the 45th Sol of its mission (Feb. 18, 2004). The hollow provides scientists with a laboratory for studying the atmospheric processes that shaped Mars because, in contrast to surrounding rocky terrain, it contains windblown dust and possibly salty clumps of soil. Spirit is scheduled to dig a trench at the bottom of Laguna Hollow on Sol 47. The image was taken by the Rover's PanCam".
