The Mars monolith is a rectangular object (possibly a boulder) discovered on the surface of Mars. It is located near the bottom of a cliff, from which it likely fell. The Mars Reconnaissance Orbiter took pictures of it from orbit, roughly 180 miles (300 km) away. The HiRISE camera that was used to photograph the monolith has a resolution of approximately 1 foot or 30 centimeters per pixel.
