Xanthe Terra is a large area on Mars, centered just north of the Martian equator. Its coordinates are 3°N 312°E / 3°N 312°E[1] and it covers 2465 km at its broadest extent. Its name means "golden-yellow land." It is in the Lunae Palus quadrangle and the Oxia Palus quadrangle. Images from Mars Express, Mars Global Surveyor, and the Mars Reconnaissance Orbiter have revealed ancient river valleys and deltas. The deltas show many thin layers just as deltas on Earth. Scientists speculate that features in Xanthe Terra show evidence of precipitation on early Mars.[2]
