Some of the weirdest and least-understood landscapes on Mars are on the floor of the deep Hellas impact basin.
- Summer is on Its Way http://hirise.lpl.arizona.edu/ESP_025916_2555
A few bright ice deposits remain sequestered in "cold traps" shadowed from the sun on the poleward-facing side of the dunes.
