469-mars-nanedi-valles-dixon – This wide-angle panoramic vista depicts the rugged interior of Nanedi Valles, a large sinuous valley located in the Lunae Palus quadrangle of Mars. The Martian canyon features steep, deeply eroded layered alcoves and terraced rocky walls, indicating ancient liquid water flow or collapse events. The arid valley floor is covered with fine wind-blown sand dunes and fractured, desiccated mud cracks beneath a dusty, salmon-colored atmospheric sky. Oil on masonite. © 2013 Don Dixon
