Slope streaks in Acheron Fossae in 2010 Dark slope streaks in Arabia Terra as seen by Mars Orbital Camera (MOC) on Mars Global Surveyor spacecraft. The darkest streaks are only about 10% darker than their surroundings. The greater apparent contrast in the image is due to contrast enhancement [1] Image is 1.65 km (1 mi) across. North is at bottom.
When occurring near the top of a dune, dark sand may cascade down the dune leaving dark surface streaks – streaks that might appear at first to be trees standing in front of the lighter regions. A new phenomenon known as slope streaks has been uncovered by the HiRISE camera on the Mars Reconnaissance Orbiter. These features appear on crater ...
Syrtis Major is the dark area projecting upward in the center right. Note orographic clouds over Olympus and Elysium Montes (left and right, respectively). No topography is visible on Mars from Earth-based telescopes. The bright areas and dark markings on pre-spaceflight-era maps of Mars are all albedo features. (See Classical albedo features ...
Dunes in Green crater, as seen by CTX camera. This is an enlargement of the previous image. Thin dark lines are dust devil tracks. The crater on the right is within Green crater. Some old glaciers are visible as arc-shaped ridges. An arrow points to one of the glaciers.
Airy-0 is a crater inside the larger Airy Crater on Mars, whose location historically defined the Martian prime meridian.It is about 0.5 km (0.3 mile) across and lies within the dark region Sinus Meridiani, one of the early albedo features to be identified on Mars.

The catalog is divided into three partial lists: List of craters on Mars: A–G; List of craters on Mars: H–N; List of craters on Mars: O–Z; Names are grouped into tables for each letter of the alphabet, containing the crater's name (linked if article exists), coordinates, diameter in kilometers, year of official name adoption (approval), the eponym ("named after") and a direct reference ...
Cerberus is dark area to left of center. Cerberus is a large "dark spot" (an albedo feature) located on Mars and named after the mythical dog Cerberus.The arcuate (curved) markings in the upper right are in the Amazonis plains and may be sand drifts.
