HiRISE 3D: Double Impact Crater!

Glacier fill in two craters now separated, but looks like the flow went north at some point, and there is a suprising lack of erosion in some areas of the rim.

HiPOD: Ridge Crossings

The simplicity of this observation contrasts with the formation we see here: two parallel, curvilinear ridges (one crossing an impact crater) that have a similar shape to other examples attributed to carbon dioxided glaciers.

HiPOD: Frosty Alcoves on Kaiser Crater Dunes

In this image, the dunes are partially free of seasonal ice, with the contrast making it easy to see the ripples. Deep alcoves have been carved at the crest of the dune.

HiRISE 3D: Celebdil, Caradhras and Fanuidhol

Sorry, these are not the three mountains of Moria, but rather three impressive peaks in the southern part of the much larger Antoniadi Crater on Mars.

HiPOD: Alluvial Fans in Mojave Crater

The landscape in this observation is pervasively eroded, right up to the tops of the ridges, with channels extending down into depositional fans much like alluvial fans in the Mojave Desert.

HiPOD: Ridges in Isidis

The objective of this observation is to study the transition area where the density of pitted cones changes significantly. Isidis Planitia is an impact basin where volcanic and fluvial/glacial landforms are abundant.

HiPOD: Layers of an Impact Crater

The objective of this observation is to examine layers in the eroded north wall of a crater. All along this wall, there appear to be layers. The layers can give us an idea of at what depth they formed.

HiRISE 3D: The Remnant Fan

In this observation, a jagged surface protrudes outward from a prominent scarp and associated spur and gully features. This is a candidate remnant fan that likely eroded during a mega flood event.
