Mars "Ups and Downs"... (shaded version)

Here, the MOLA Altimetry is cast as a 3-D model, a shaded relief map illuminated from the upper right.

BEWARE: this lighting can not ever happen on Mars!

The large volcanos stand out beautifully, as do the impact basins of Hellas and Argyre. Also clear here is how flat the Northern Plains really are (remnants of an ocean basin?), the incredible number of craters on the Highlands, and the distinct difference in elelvations between the Highlands and the Lowlands.
