About this work
This image from NASA Mars Reconnaissance Orbiter shows a portion of a long valley system in northern Arabia Terra. The valley must be relatively young because it cuts through the ejecta of an impact crater that still retains it entire ejecta blanket, indicating the crater is also fairly young and fresh. The valley is interesting because it transitions to an inverted channel near its end point. Inverted channels form when a valley fills with materials.
