This image from HiRISE image PSP_003294_1895 shows a portion of the Athabasca
Valles channel system. Part of a streamlined "island" is visible on the
right, and dune-like landforms that occur on the channel floor can be seen
on the left. At higher resolution it is apparent that a thin layer of
solidified lava coats both the dune-like landforms and the topographically
higher streamlined island. Two impact craters within the subscene can be
identified by the relatively bright-rayed ejecta that surround them. Most
of the region is dusty and, therefore, fairly uniform in color. However,
blue tinges in the HiRISE false color data delineate scarps that are too
steep for dust to accumulate. One such scarp appears where a narrow
fracture cuts through the streamlined island. Another appears on the
topographic step at the edge of the streamlined island.
