.
The shape of a crater can depend on factors including the angle of
impact and the pre-impact slope and topography.
o Valley Networks in the Ancient Martian Highlands
http://hirise.lpl.arizona.edu/ESP_045299_1545
The valley networks on Mars are terrains eroded by flowing water
billions of years ago.
o Frosted Dunes

Sand dunes cover much of this terrain, which has large boulders lying
on flat areas between the dunes.
