Hydrological characteristics of recurrent slope lineae on Mars: Evidence for liquid flow through regolith and comparisons with Antarctic terrestrial analogs

On the basis of their morphology and seasonal thermal characteristics, recurrent slope lineae (RSL) on Mars have been inferred to be a possible result of the flow of a liquid (likely a saline brine) through the upper portions of the martian regolith. In this note, we analyze repeat HiRISE imaging of...
