Arsia Mons is an extinct shield volcano in the Tharsis region near the equator. It is part of the Tharsis Montes group of volcanos. Its location is 8.35 S and 120.09 W (239.91 E) in the Phoenicis Lacus quadrangle. Its name is a classical feature name and comes from a corresponding albedo feature on a map by Giovanni Schiaparelli, which he named in turn after the legendary Roman forest of Arsia Silva.[1] Researchers have found much evidence for glaciers on Arsia Mons.[2] [3]

Caves

Seven cave entrances have been discovered on the sides of Arsia Mons. These caves could contain reserves of water ice or even life. They are possible locations for a cave settlement. With the low gravity of Mars, lava tubes may be over 800 feet in width. A lava tube on Mars could protect colonists from meteorites and radiation. Because of the lack of a magnetic field at present, Mars has a fair amount of radiation, especially from cosmic ray sources.[4] A mini-series produced by National Geographic in 2016 depicted how people could establish a base in a cave.[5] [6]

Possible cave entrances These openings have been named (A) "Dena," (B) "Chloe," (C) "Wendy," (D) "Annie," (E) "Abby" (left) and "Nikki," and (F) "Jeanne."

Clouds

Repeated Clouds over Arsia Mons [7] there is some debate about the nature of the clouds whether they are dust particles or water vapor [8] If this is in fact Water Vapor, that indicates the presence of Water Ice around Arsia Mons. [9] [10]

Possible cave entrance to pit


Valentine Cave in Lava Beds National Monument, California. This shows the classic tube shape; the grooves on the wall mark former flow levels. Pits near volcanic regions of Mars may be openings to caves like this.
