Angustus Labyrinthus is a complex of intersecting valleys or ridges near the Martian south pole (in the Mare Australe quadrangle), located at 81.68° S and 63.25° W.It was nicknamed the "Inca City" by NASA scientists due to its superficial resemblance to a ruined city. [1]
Planum Australe (Latin: "the southern plain") is the southern polar plain on Mars.It extends southward of roughly 75°S and is centered at The geology of this region was to be explored by the failed NASA mission Mars Polar Lander, which lost contact on entry into the Martian atmosphere.
The Mare Australe quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The Mare Australe quadrangle is also referred to as MC-30 (Mars Chart-30). [1] The quadrangle covers all the area of Mars south of 65°, including the South polar ice cap, and its ...
1995 photo of Mars showing approximate size of the polar caps. The planet Mars has two permanent polar ice caps of water ice and some dry ice (frozen carbon dioxide, CO 2).Above kilometer-thick layers of water ice permafrost, slabs of dry ice are deposited during a pole's winter, [1] [2] lying in continuous darkness, causing 25–30% of the atmosphere being deposited annually at either of the ...
The Dorsa Argentea Formation (DAF) is thought to be a large system of eskers that were under an ancient ice cap in the south polar region of Mars. [1] The ancient ice cap was at least twice the size of the present ice cap and may have been 1500–2000 meters thick. [2]
Frosted terrain on Utopia Planitia, taken by the Viking 2 lander in 1979. Utopia Planitia (Greek and Latin: "Utopia Land Plain") is a large plain [2] within Utopia, the largest recognized impact basin on Mars [a] and in the Solar System with an estimated diameter of 3,300 km (2,100 mi). [1]

The basin is approximately 1,700 km (1,100 mi) wide [1] and drops 5.2 km (17,000 ft) below the surrounding plains; it is the second-deepest impact basin on Mars after Hellas. The crater Galle , located on the east rim of Argyre at 51°S 31°W / 51°S 31°W / -51; -31 , strongly resembles a smiley
