Bahram Vallis is an ancient river valley in the Lunae Palus quadrangle of Mars at 20.7° north latitude and 57.5° west longitude. It is about 302 km long and was named after the word for 'Mars' in Persian.[1] Bahram Vallis is located midway between Vedra Valles and lower Kasei Valles. It is basically a single trunk valley, with scalloped walls in some places. The presence of streamlined erosional features on its floor shows that fluid was involved with its formation.[2]
