This HiRISE image (PSP_0 03379_1835) is along the rim of an impact crater in Meridiani and shows a lighter-toned base unit with more resistant dark-toned ridges on top.

Both units exhibit complex fracture patterns. Also evident are old dune fields that have been solidified and then fractured, as well as younger, non-solidified dune fields.

More recently, the entire area has been deeply eroded by the wind.
