I stumbled upon the European Space Agency (ESA) site and found cool pictures of the surface of Mars. The image at this link was one I spent a little time looking over.
'It is of the Deuteronilus Mensae region... The area is located on the northern edge of Arabia Terra and borders the southern high- and northern lowlands, at approximately 39° North and 23° East.'
At the very bottom, off center to the right I found an interesting feature, FOLDING.
In the center of the 'round' feature appears a fold string (shortening direction) trending northwest, south east. While this doesn't seem too exciting, it does add evidence of plastic deformation has/does occur(ed) on the planet. It also suggests: active tectonics; temperatures high enough to soften the rock; high pressures and also liquids. Liquids because adding liquid reduces the temperatures and pressures needed to soften rocks and is frequently present here on Earth.
*Of course it may not be a fold at all and I am just spewing prophecies of ignorance. Which is fun just the same.

I want to have a trip to Mars bevor I die.
