About this work
This image shows a cross-section of ancient canyon systems in east Coprates Chasma, and displays several orders and generations of wind-driven dunes and ripples, also called bedforms. Some areas display more modern bedforms, often termed mega-ripples, which have likely been active over long timescales and have migrated in the recent past. Other areas along the canyon wall have larger bedforms that show a very different appearance.
