TES has detected gray hematite and CRISM sees kieserite along this crater wall and floor. The scene is located in Capri Chasma, at the eastern end of the Valles Marineris canyon system.
Image cutout is less than 5 km (3 mi) across and the spacecraft altitude was 264 km (164 mi). For full observation details including images with scale bars, visit the source link.

From a distance, the floor of this crater looks like a giant honeycomb or spider web. The intersecting shapes, or polygons, commonly occur in the northern lowlands of Mars.
The polygons in this “patterned ground” are easy to see because their edges are bound by troughs or ridges covered by bright frost relative to their darker, frost-free interiors. Patterned ground on Mars is thought to form as the result of cyclic thermal contraction cracking in the permanently frozen ground.
Image cutout is less than 5 km (3 mi) across and the spacecraft altitude was 314 km (195 mi). For full observation details including images with scale bars, visit the source link.

One of the most eye-catching aspects of this scene are the intricate swirls that these layers form. Sedimentary rock generally accumulates in horizontal layers. These layers, however, have been folded into the patterns that we see today. Folding of the layers that are exposed here may have occurred due to the weight of overlying sediments.

This is a streamlined island, one of many observed in the large outflow channels on Mars. This outflow channel is called Kasei Valles, and is one of the largest catastrophic outflow channels on Mars. The streamlined island forms as water flows through the channel, but is blocked by some sort of obstacle, such as a crater or other topographic landform.

This observation covers the Martian surface just to the east of the 150 kilometer-diameter Holden Crater in southwestern Margaritifer Terra.
The image reveals a very complex terrain, with what appear to be very blocky or polygonally fracture materials interspersed with other materials also standing in relatively high local relief. The entire surface appears etched and the blocky or fracture materials may lie on top of the sequence.
Image cutout is less than 5 km (3 mi) across and the spacecraft altitude was 260 km (162 mi). For full observation details including images with scale bars, visit the source link.
