| The projections are Mercator to 70°
latitude and stereographic at the poles with the south pole at left and
north pole at right. Note the elevation difference between the northern
and southern hemispheres. The Tharsis volcano-tectonic province is centered
near the equator in the longitude range 220° E to 300° E and contains
the vast east-west trending Valles Marineris canyon system and several major
volcanic shields including Olympus Mons (18° N, 225° E), Alba Patera
(42° N, 252° E), Ascraeus Mons (12° N, 248° E), Pavonis
Mons (0°, 247° E), and Arsia Mons (9° S, 239° E). |

Other regions and structures include Solis
Planum (25° S, 270° E), Lunae Planum (10° N, 290° E), and
Claritas Fossae (30° S, 255° E). Major impact basins include Hellas
(45° S, 70° E), Argyre (50° S, 320° E), Isidis (12°
N, 88° E), and Utopia (45° N, 110° E). This analysis uses an
areocentric coordinate convention with east longitude positive. Note that
the color scale saturates above 8 km. (Credit: MOLA Science Team) |
