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]
The south pole region features many craters and basins such as the South Pole–Aitken basin, which appears to be one of the most fundamental features of the Moon, [7] and mountains, such as Epsilon Peak at 9.050 km, taller than any mountain found on Earth. The south pole temperature averages approximately 260 K (−13 °C; 8 °F).
Despite being deeper than the Moon's South Pole-Aitken basin, Hellas' rim peaks are significantly less prominent. This may be because large Martian impacts such as Hellas induced global hot rainfall and meltwater flows that degraded crater rims, including their own. [ 11 ]

Near the center of the crater floor is a small ridge. The floor of the crater has an average depth of 4 km and it is 60 km across. The slope of the crater walls is 10–15°. [1] Because of the crater's location near the lunar south pole, the main part of the crater is illuminated by the Sun during only 25% of each lunar day.
The rotational axis of the Moon passes through Shackleton, near the rim. The crater is 21 km (13 miles) in diameter and 4.2 km (2.6 miles) deep. [2] From the Earth, it is viewed edge-on in a region of rough, cratered terrain. It is located within the South Pole–Aitken basin on a massif. [3]
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]
Mars's north celestial pole is also only a few degrees away from the galactic plane. Thus the Milky Way, especially rich in the area of Cygnus, is always visible from the northern hemisphere. The South celestial pole is correspondingly found at 9 h 10 m 42 s and −52° 53.0′, which is a couple of degrees from the 2.5-magnitude star Kappa ...
