Sedimentary / Layering Processes.
Samara Valles is one of the longest ancient valley systems on Mars. This system traverses over 1000 kilometers towards the northwest across the heavily cratered Southern highlands eroding into the gentle slopes of Terra Meridiani. The valley terminates in the Northern lowlands within the Chryse Basin where both Viking Lander 1 and Pathfinder are located.
