December 8, 2010
A sea of dark dunes, sculpted by the wind into long lines, surrounds the northern polar cap covering an area as big as Texas.
December 8, 2010
A vast dune field lies near the northern polar cap of Mars. Seen here in summer, the dunes have partially buried an impact crater about 1,000 meters (3,300 feet) wide.

Although it is 45 kilometers (28 miles) wide, countless layers of ice and dust have all but buried Udzha Crater.
December 8, 2010
West of Valles Marineris lies a checkerboard named Noctis Labyrinthus, which formed when the Martian crust stretched and fractured.
