This image from NASA's Mars Odyssey spacecraft shows the Olympica Fossae channel system located east of the Olympus Mons volcano in Tharsis. These anastomosing channels cut numerous lava flows indicating that the channels are younger than the lava flows.

The mottled surface texture and flow features observed in this NASA Mars Odyssey image suggest materials may be, or have been, mixed with ice. There is also evidence in some areas for infilling of sediments as crater rims and ridges appear covered.

Surface Erosion and Flow

The small mounds with summit depressions in the northern part of this NASA Mars Odyssey image have an unknown origin. Some scientists think they may be cinder cones, while others think they may be pseudocraters, formed by the interaction of lava and ice.

Acidalia Planitia

Interesting textures on lava flows in Daedalia Planum, southwest of the Tharsis volcanoes, can by observed in this image from NASA's Mars Odyssey spacecraft.

Daedalia Planum

This image from NASA's Mars Odyssey spacecraft shows a flooded crater in Amazonis Planitia. This crater has been either flooded with mud and or lava. The fluid then ponded up, dried and formed the surface textures we see today.

In this image from NASA's Mars Odyssey spacecraft showing a location about 1,000 km (620 miles) west of the massive Elysium volcanic complex, a system of branching troughs shows a continuum of features that provides clues to its origin.

Hebrus Valles

The eroded, layered deposit in this NASA Mars Odyssey image of Gale Crater is a mound of material rising 3 km (about 2 miles) above the crater floor. It has been sculpted by wind and possibly water to produce the dramatic landforms seen today.

Gale Crater Mound

In this image from NASA's Mars Odyssey, eroded mesas and secondary craters dot the landscape in an area of Cydonia Mensae. The single oval-shaped crater displays a 'butterfly' ejecta pattern, indicating that the crater formed from a low-angle impact.

Cydonia Craters

The floor of the crater in this NASA Mars Odyssey image displays interesting textures and it appears to have been flooded by some type of material. It is unclear if this material was fluvially emplaced mud (hyperconcentrated flows) or lava.

Flooded Crater in Terra Sirenum

Pavonis Mons is the middle of the three large volcanoes on the Tharsis bulge. This image from NASA's Mars Odyssey spacecraft covers the edge of the volcano's caldera. Outside of the caldera, numerous lava flows and impact craters can be seen.

Just north of the hematite deposit in Meridiani Planum, the remnants of a formerly extensive layer of material remain as isolated knobs and buttes in this image from NASA's Mars Odyssey spacecraft.

Dunes in the Vastitas Borealis region of Mars are seen in this image from NASA's Mars Odyssey spacecraft. These sand seas migrate around the north polar cap following the strong polar vortex winds.

The smooth plains of Elysium embay the blocky broken up highlands of Aeolis in this image from NASA's Mars Odyssey spacecraft. The plains have been interpreted by researchers to be possibly mudflows or lava flows.

This image from NASA's Mars Odyssey spacecraft shows part of Ganges Chasma in Valles Marineris. The colors indicate compositional variations in the rocks exposed in the wall and floor of Ganges and in the dust and sand on the rim of the canyon.

NASA's Mars Odyssey spacecraft produced this gamma ray spectrometer map, which is centered on the north pole of Mars and based on gamma-rays from the element hydrogen. In this region, hydrogen is mainly in the form of water ice.

An unusual mix of textures is featured in this image from NASA's Mars Odyssey spacecraft of a surface east of the Phlegra Montes. Scabby mounds, commonly occurring around degraded craters, mix with a more muted, knobby terrain.

With its rim eroded off by catastrophic floods in Tiu Vallis and its strangely angular shape, this 12 km (about 7.5 mile) diameter crater imaged by NASA's Mars Odyssey spacecraft looks vaguely like a stop sign.

The wind-sculpted yardangs in this scene from NASA's Mars Odyssey spacecraft are part of the Medusae Fossae Formation, a regionally extensive geologic unit that probably was produced from the accumulation of volcanic ash.

Memnonia Sulci

The long sharp-crested features observed in this image from NASA's Mars Odyssey spacecraft are named yardangs. Yardangs form by wind erosion and typically lie in the direction of the dominant wind.

The top half of this NASA Mars Odyssey image shows interior layered deposits that have long been recognized in Valles Marineris. Upon close examination, the layers appear to be eroding differently, indicating different levels of competency.
