Mamers Vallis

October 12, 2009
This sinuous channel begins at the edge of Cerulli Crater in northern Arabia and snakes its way across 1000 km of cratered highlands before reaching Deuteronilus Mensae at the boundary of the northern lowlands. The fluid that carved the channel, either lava or water, flowed from the bottom of this scene to the top. The quasi-streamlined features on the channel floor may have nothing to do with flow and instead may be due to a permafrost creep process.
