- Martian Honeycomb Hideout http://hirise.lpl.arizona.edu/ESP_024061_2610
The most striking aspect of this image is the honeycomb-like pattern of the dunes.
- Defrosting of Dunes with Large Gullies http://hirise.lpl.arizona.edu/ESP_024103_2565
The gullies at this site are particularly large, which is intriguing, suggesting that this site be monitored to see if stages of gully formation or details of activity can be observed.
- A Sinuous Ridge South of Moreux Crater http://hirise.lpl.arizona.edu/ESP_024224_2190
This observation shows a sinuous ridge that may be an inverted stream. Streams can be inverted if they are made of stronger material than their surroundings.
- Looking for Changes in Colorful Aureum Chaos http://hirise.lpl.arizona.edu/ESP_030675_1765
Although Mars has a thin atmosphere, the wind is nevertheless strong enough to move some sand dunes and ripples, collectively termed "bedforms."
