ESP_069234_1890  Science Theme: Sedimentary/Layering Processes
This image shows a layered rock formation within Jiji Crater that has eroded into buttes and stair-like layers.

This formation extends west and east. Similar layered rocks are within several craters in Arabia Terra and Meridiani Planum, including Sera and Banes craters. The similarities suggest that the same process was forming deposits over a large geographic area long ago. Our image also indicates that much of the formation has eroded away relative to what has remained.

Multiple HiRISE images within Jiji Crater allow scientists to evaluate how similar or different layers are over this area, which can help them understand geologic layers and their properties over greater distances.
