The red cliffs of Mars
Last week the Mars Reconnaissance Orbiter team released this beautiful image of what they call “layered yardangs” on Mars.
What creates these sharp ridges? This layered terrain has been sculpted by the wind. The aligned ridges are called yardangs, which are formed in areas where the dominant erosional force is the wind. Yardangs are also found on Earth, usually in very dry areas.
What I see are majestic red cliffs rising out of a aqua-colored sand desert. What a place to visit!
