Polygonal Surface Patterns at the South Pole

Like Earth, Mars has concentrations of water ice at both poles. Because Mars is so much colder, however, the seasonal ice that gets deposited at high latitudes in the winter and is removed in the spring (generally analogous to winter-time snow on Earth) is actually carbon-dioxide ice.

Diffuse Winter Lighting of the Chasma Boreale Scarp

Sunlight was just starting to reach the high Northern latitudes in late winter when HiRISE captured this image of part of the steep scarps around portions of the North Polar layered deposits. (Audio by Tre Gibbs. Enhanced color images are 1 km across.)

Possible Cyclic Bedding within a Crater in Arabia Terra

Cyclic bedding" refers to a pattern of layering caused by repeated fluctuations in the amount of available sediment that creates new rock layers. These fluctuations are caused by long-term changes in the region's climate (Audio by Tre Gibbs. Enhanced color images are 1 km across.)
