Wrinkle Ridges
Many areas of Mars show wrinkles on the surface, called wrinkle ridges. They are elongated and are often found on smooth area of Mars. Because they are wide, gentle topographic highs, they are sometimes hard to see. Although first thought to be caused by lava flows, they are now generally thought to be more likely caused by compressional tectonic forces that cause folding and faulting. A wrinkle ridge is visible in the image to the right of Ares Vallis.

Famous quotes containing the word wrinkle:
“Shorten my days thou canst with sullen sorrow,
And pluck nights from me, but not lend a morrow;
Thou canst help time to furrow me with age,
But stop no wrinkle in his pilgrimage.”
