HiRISE captured this image of an eroded mesa made famous by its similarity to a human face in a Viking Orbiter image with much lower spatial resolution and a different lighting geometry.

HiRISE is also offering this observation in its HiccdStitch form, with raw image geometry and North is down:

Observation Geometry

Image PSP_003234_2210 was taken by the High Resolution Imaging Science Experiment (HiRISE) camera onboard the Mars Reconnaissance Orbiter spacecraft on 05-Apr-2007. The complete image is centered at 40.7 degrees latitude, 350.5 degrees East longitude. The range to the target site was 299.4 km (187.1 miles). At this distance the image scale is 29.9 cm/pixel (with 1 x 1 binning) so objects ~90 cm across are resolved. The image shown here has been map-projected to 25 cm/pixel and north is up. The image was taken at a local Mars time of 03:28 PM and the scene is illuminated from the west with a solar incidence angle of 73 degrees, thus the sun was about 17 degrees above the horizon. At a solar longitude of 213.4 degrees, the season on Mars is Northern Autumn.
