Let's rocket to Mars, courtesy of the UA Lunar and Planetary Lab's HiRISE camera aboard the Mars Reconnaissance Orbiter. Here's a shot of Active Gullies in Crater Dune Field, Southern Polar Region. Mmmm, polar. Makes me wish I was eating Klondike bar on Mars right now.
These dune gullies are located in an unnamed crater just north of the Richardson Crater, which also contain dune gullies.
HiRISE is monitoring the seasonal activity of gullies in this location and in other dune fields in the southern midlatitudes and northern polar region.
