Interpreting Martian paleoclimates from valley network morphologies: insights from terrestrial analogues in Egypt

Morphogenetic classification of Martian landforms has provided a context for the inference of surface processes and paleoclimatic conditions on Mars [1][2][3][4][5][6]. The complexity of extensive valley network patterns (Figure 1) suggests that fluvial conditions formerly existed on Mars [7]; however, surface reworking and the lack of absolute age control complicates the precise definition of this time period.
