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:
“I have, as when the sun doth light a storm,
Buried this sigh in wrinkle of a smile;
But sorrow that is couched in seeming gladness
Is like that mirth fate turns to sudden sadness.”
—William Shakespeare (1564–1616)
