Labou Vallis is a valley in the Memnonia quadrangle of Mars, located at 8.7° south latitude and 154.5° west longitude. It is 222 km long and was named after a French word for Mars.[1] Labou Vallis has dark slope streaks on its walls. The streaks are generally thought to be the dark material that has been exposed by bright dust moving down a steep slope in an avalanche.
