description
Shalbatana Vallis is located in the highland region of Xanthe Terra , within the Oxia Palus Gradfeld. Its beginning lies in a zone of chaotic terrain at 0 ° latitude and 46 ° west longitude - inside the 116 km wide Orson Welles crater - and ends in the lowlands of Chryse Planitia . It is the westernmost of the outflow valleys that flow south into the Chryse Plain. The valley contains the first evidence of the existence of a coastline on Mars; it was part of a former lake, which had an area of 210 km² and a depth of 460 m. In a study based on the HiRISE images, it was found that the flowing water cut a 48 km long canyon into the eroded valley, depositing sediments and forming a river delta . Both the delta and the rest of the area are believed to be evidence of a long-standing lake that was formed during a warm and very humid period on Mars.
