This image shows lineated valley fill and lobate debris aprons in the Deuteronilus Mensae region. Many of the valley floors in this region exhibit complex alignments of small ridges and pits often called "lineated valley fill". The cause of the small-scale texture is not well understood, but may result from patterns in ice-rich soils or ice loss due to sublimation (ice changing into water vapor).
In case you thought astrophysics wasn't awesomely interesting. I love looking at the other galaxies.
