Canyon Lake (Mars)
Reference work entry
Rift paleolake (Mangold and Ansan 2006).
Formation models of canyon lakes:
Low-standing shallow canyon lakes or playas (Lucchitta 1982). These may have been recharged in the subsurface from the global groundwater table derived from the polar ice.
High-standing km-deep water-filled canyon lakes, probably ice covered. Possible lacustrine deposits ( interior-layered deposits) have been identified within canyons and valleys on volcanoes, at a higher elevation than the base of the polar-layered deposits, precluding the possibility that – unlike crater lakes – these lakes received water from the global groundwater system derived from the basal melting of ice-rich polar deposits (Carr 2002). Possible local sources...
