Boulders on a hill in Utopia Planitia, Mars

Mars
This image shows a boulder covered hill at 41 N, 207 W in the Utopia Planitia region of Mars. The image is about 2.2 km across and 3.3 km high. The boulders are the small specks on the top of the hill and are thought to be the remains of a layer of harder rock which was broken up and largely eroded away. North is approximately up, the local solar time is roughly 6:00 p.m. and the scene is illuminated from the left. (Mars Global Surveyor, MRPS94109)
