This observation features an impact crater with a furrowed and pitted floor and a big, slump-like feature in its northern part. The crater floor is reminiscent of formations believed to be of glacial origin elsewhere on Mars, and our HiRISE image can provide clues to its nature. The terraced wall of the crater has blocky material reminiscent of craters...

This approximately 190-meter diameter circular depression appears to have an interesting interior shape in Context Camera data. This observation will assist in confirming that this is an impact crater and to determine what is causing the unusual interior appearance in the CTX data. (NASA/JPL-Caltech/UArizona)

Cataracts are large landforms, and this oblique image covers only a small area of the innermost channel. (NASA/JPL-Caltech/UArizona)

What look like scratch marks in this picture are revealed, thanks to HiRISE resolution, to be linear gullies. (NASA/JPL-Caltech/UArizona)

There are many theories about the formation of sinuous ridges on Mars. Some theories suggest these may be inverted streambeds, while others indicate they may be a glacial feature called an esker. Closer inspection of this feature may help scientists determine if this is an inverted stream bed or an esker. (NASA/JPL-Caltech/UArizona)

HiRISE often rides along with observations performed by the Context Camera (CTX) also on the Mars Reconnaissance Orbiter. (NASA/JPL-Caltech/UArizona)
