HiRISE: Semi-sinuous ridge and stratified material in Arabia Terra
Semi-sinuous ridge and stratified material in Arabia Terra. Looks like inverted stream channels that contributed to a lake or pond, with stratified sedimentary rock units in the depression. Important imaging for understanding how to best distinguish cratered, erosion-resistant sedimentary rock … Continue reading

HiRISE: Stair-stepped hill in central Arabia Terra
Stair-stepped hill in central Arabia Terra. Stratified material eroded so as to look something like a wedding cake. A cliff-bench slope expression, apparently mantled with dust, each layer is roughly the same thickness as the next. Beautiful Mars series. [More … Continue reading
