TheTinia Valles are a set of channels in an ancient valley in theMemnonia quadrangle of Mars, located at 4.7° south latitude and 149° west longitude. They are 18.7 km long and were named after a classical river in Italy.[1] The associated valley has manydark slope streaks on its walls. These features are widely believed to be avalanches of a thin layer of bright dust that usually covers the dark surface beneath.
