Laser Topography of Mars Northern Ice Cap

Caption

Morphology of the north polar region of Mars. Spiral troughs are seen throughout the ice-rich polar cap (quasi-circular dome at center), and Chasma Boreale is the large canyon dividing the polar cap into two lobes. Chasma Boreale is the size of the Grand Canyon in the US and up to 2 kilometers deep. Shaded-relief image based on Mars Orbiter Laser Altimeter data.
