Naming adopted by the IAU on September 26, 2012 after a "River in British Columbia and Alberta, Canada".[1]

Peace Vallis is an outflow channel in Gale Crater in the Aeolis quadrangle on the planet Mars; it appears to have been carved by fluids, perhaps water.[2][3][4] The valley 'flows' southeast down out of the hills of Gale Crater to Aeolis Palus below near "Mount Sharp" and is centered 4°13′S 137°14′E / 4.21°S 137.23°E / -4.21; 137.23.[1] Peace Vallis is near the landing site ("Bradbury Landing") of the Curiosity rover which started studying the valley in 2012. The name, Peace Vallis, was officially adopted by the IAU on September 26, 2012.[1]
