...., Lapotre et al., 2016b ). For example, tributary valleys of Nanedi Valles and Nirgal Vallis, Mars, are often cited as evidence for groundwater-seepage erosion solely based on morphology ( Harrison and Grimm, 2005 ), but they are most likely incised into layered volcanic bedrock. Similar tributary valleys...
