Geologic Map of Mars

[Oafman]

Here's one for astrogeologists. The USGS, in their awesomeness, have compiled a wide range of data into an unprecedently detailed geologic map of the Red Planet.

Geoplogic map of mars (pdf)

As if the map wasn't cool enough, the associated pamphlet (pdf) talks you through how the data was obtained and compiled, and also about the geologic epochs of Mars.

(Also, there's no Earth/Exo Sciences category in the prefixes; it was a toss up between physics and chemistry, and physics won. Though on reflection, 'Space' would probably have been a reasonable choice...!)
