The southernmost member of this group of shield volcanoes is called Arsia Mons (the other two being Ascraeus Mons
and Pavonis Mons).
That would make Mars's giant mid-latitude mountains -- Ascraeus Mons
, Pavonis Mons and Arsia Mons.
The High Resolution Imaging Science Experiment camera aboard NASA's Mars Reconnaissance Orbiter found the heart-shape on the south of the huge shield volcano Ascraeus Mons
which measures approximately 200 meters across, Discovery News reported.
Morning clouds and frost can sometimes settle in the broad, low plains of this region, making the giant Tharsis volcanoes Arsia Mons, Pavonis Mons, and Ascraeus Mons
, as well as nearby Olympus Mons, appear as dark spots above the bright plains.
of Noctis Lacus or Syria Planum (aka Nox Lux), and over Arsia Mons in the south and Lunae Lacus and Ascraeus Mons
in the north, the martian 'W' cloud is formed.
Combined with the varying height of the volcanoes, we can say that Arsia Mons is the oldest, then Pavonis Mons formed and finally Ascraeus Mons
," said Mikael Beuthe of the Royal Observatory of Belgium and lead author of the paper.
of Noctis Lacus (Syria Planum, 'Nox Lux') and Arsia Mons in the south and Lunae Lacus and Ascraeus Mons
in the north can join to form the streaks of the martian 'W' cloud.
In mid-November 2009, during early northern spring, observers detected bright clouds over the four great volcanoes of the Tharsis Bulge: Olympus Mons, Ascraeus Mons
, Pavonis Mons, and Arsia Mons.
of Noctis Lacus ('Nox Lux'), Arsia Mons in the south, and Lunae Lacus and the Ascraeus Mons
orographic in the north.
The 270-km long Martian channel near the Ascraeus Mons
volcano does not seem to have been made by water.
Bleacher and his colleagues carried out a careful study of a single channel on the southwest flank of Mars' Ascraeus Mons
volcano, one of the three clustered volcanoes collectively called the Tharsis Montes.

to Arsia Mons: our first record of these at Ls = 93[degrees].
