A simulation of an ancient ice age era on Mars 2.1 million to 400,000 yrs ago using Mars Global Surveyor and Viking Orbiter imagery. Variations in the axial tilt contributed greater seasonal variation and atmospheric movement of water vapor leading to the widespread ice deposits and glaciation of the mid-latitudes to 30 degrees N and S.

A global reference map of the Planet Mars. Pretty nice find actually (although I found one typo…”Arsai Mons”, in the Western Hemsiphere should actually be “Arsia Mons”)

Taking a break from writing a paper…more for International Mountain Day.

At approximately 73,920ft (base-to-peak), it is the largest planetary mountain structure in the Solar System…Olympus Mons.


Because of the apparent lack of plate tectonics on Mars, Olympus Mons is thought to have formed from a hotspot in the crust which simply continued to spew out lava and build the shield volcano up to its absurd size. This is unlike Hawaii, which also features a hotspot in the oceanic crust, but tectonic movements formed an island chain as opposed to one gigantic volcano.


Is the volcano still active? Recent evidence by the Mars Express Orbiter suggest the answer is yes. There is evidence of law flows between 115 million years to as recent as 2 million years old. Meaning, the volcano’s last eruption may have been when early forms of humans were walking the Earth and before that, when dinosaurs roamed. Major volcanism is clearly much rarer on Mars as it is an internally cooler planet, but it is far from geologically dead. The calderas of Olympus Mons are estimated to be between 350 and 150 million years old, indicating the volcano is geologically young.
