- Layered Material Cut by a Valley Connected to East Jezero Crater http://hirise.lpl.arizona.edu/ESP_026359_1990
This image shows layered bedrock composed of light- and intermediate-toned materials.
- Active Sand Abrasion in the Northern Polar Region of Mars http://hirise.lpl.arizona.edu/ESP_026839_2550
The large dune field which surrounds Mars' North Polar cap is actively being modified by the wind, with dunes moving at rates of a meter or more per year.
- Streaks on the North Polar Layered Deposits http://hirise.lpl.arizona.edu/ESP_026897_2655
These streaks may be formed by winds blowing bright water frost over the surface, removing frost from the surface, or blowing dark material over the frost.
- Pluvo Point http://hirise.lpl.arizona.edu/ESP_026956_2545
Although we can clearly see the bright area in this image, it isn't due to frost or ice at this time of year.
