Image:Layers in a crater in Arabia.JPG|Layers in [[Tikonravev Crater]] in Arabia, as seen by [[Mars Global Surveyor]] (MGS). Layers may form from [[volcanoes]], the wind, or by deposition under water. The craters on the left are pedestal craters. Some researchers believe this crater once held a massive lake.

Image:Tikhonravov Basin Streaks.JPG|Tikhonravov Basin streaks, as seen by HiRISE. Scale bar is {{convert|500|m|ft|abbr=on}} long
Image:Layers in Monument Valley.jpg|Layers in Monument Valley, Arizona. These are accepted as being formed, at least in part, by water deposition. Since Mars contains similar layers, water is considered a major cause of layering on Mars.
Image:Henry Crater Mound.JPG|[[Henry Crater]] mound, as seen by HiRISE. The scale bar is {{convert|500|m|ft|abbr=on}} long
Image:Cassini crater floor.JPG|Crater in the middle of [[Cassini (Martian crater)|Cassini]], as seen by HiRISE. Layers may have been deposited under water since it is believed that Cassini once held a giant lake.

Image:ESP 025558buttes.jpg|Buttes, as seen by HiRISE under [[HiWish program]]. Buttes have layered rocks with a hard resistant cap rock on the top which protects the underlying rocks from erosion.
