The Vedra Valles are a set of channels in an ancient river valley in the Lunae Palus quadrangle of Mars, located at 19.4° N and 55.6° W. They are 115 km long and were named after an ancient river in Great Britain.[1]
Together with other ancient river valleys, they have provided strong evidence for a great deal of running water on the surface of Mars.[2] [3] [4]
