Martian aquifers Archives

Topography of Mars derived from Mars Orbiter Laser Altimeter (MOLA) aboard the Mars Global Surveyor (MGS) mission (Smith et al., 1999). Hellas and Argyre impact basins are labeled along with the northern lowlands. Three mean shoreline elevations are taken from Parker et al. (1989) and Carr and Head (2003). Argyre and Hellas impact basins are outlined at an elevation of −2090 m.
