These dark, narrow channels called (SRL) recurring slope lineae emanate from the walls of Garni Crater on Mars. The dark channels here reach a length of hundreds of meters. It is hypothesized that they were formed by the flow of brackish water on Mars, as photographed by the MRO spacecraft. Credits: NASA/JPL/University of Arizona
