The Olympica Fossae are a set of troughs in the Tharsis quadrangle of Mars at 25° north latitude and 114.1° west longitude. They are about 420 km long and were named after an albedo feature at 17N, 134W.[1] Parts of the fossae have been suggested to be both outflow channels as well as channels for flowing lava, routing both molten rock and catastrophic outburst floods of water at different times in Mars' geological past.[2]
