Layered polar terrain on Mars

Layered polar terrain on Mars

Fig. 8.12 . These layers, exposed in the south polar residual cap of Mars, consist of bright ice and dark, fine dust deposited over millions of years. The layered terrain in both the north and south residual caps is thought to contain detailed records of the climate history of Mars. This image covers an area of 10 by 4 kilometers. It was taken from the Mars Global Surveyor in October 1999 at 87 degrees south and 10 degrees west, near the central region of the residual south polar cap. (Courtesy of NASA/JPL/MSSS.)
