How did this folding occur? On Earth, rocks are commonly folded when deeply buried and subject to high heat and pressure, which can make any rock flow.
This image covers the margin of a lava flow in Elysium Planitia, the youngest flood-lava province on Mars, and highlights terrain that resembles an elephant.
The differing colors indicate different rock types of alteration. The darkest patches of ground probably consist of volcanic sand that is trapped in relative low areas.
Every winter, dunes and other surfaces at these northern latitudes are coated with several tens of centimeters of carbon dioxide frost and ice, plus a minor amount of water frost.
Gullies remain an interesting feature to study on Mars, especially because we are still learning about their formation and what processes still act on them.
This observation was taken to investigate the topography near the source of fluids from the Cerberus Fossae fractures in the Elysium Planitia region of Mars.
