HiPOD: A Rippled Patch on the Plains

Here on the plains to the west of Juventae Chasma, we see a patch of inverted, or perhaps fluvial, channel forms with superposed or decaying-in-place bedforms that have been acted upon by the wind. This patch is surrounded by a more heavily cratered darker-toned terrain. Is the patch maybe just comprised of sedimentary materials?
