MARS RECONNAISSANCE ORBITER HIRISE IMAGES
July 11, 2012
o Light-Toned and Possible Hydrated Materials in Gullied Crater
This observation shows a gullied crater in the Southern mid-latitudes
with light-toned deposits near the center of its floor.
o Well-Preserved Impact Crater with Ridges
Although the rim of this well-preserved crater and its smooth walls
are very impressive, so is the spectacular collection of ridges draping
o Northern Polar Dune Field
These dunes, known as barchan dunes, usually form where there is a
moderate supply of sand and a prevailing wind direction.
o Polar Cliffs and Falling Blocks
There is an ice sheet at the North Pole of Mars that is a few miles thick
at its center, and at some places it ends in steep cliffs.
All of the HiRISE images are archived here:
