9 Polar Lakes, Streams, and Springs as Analogs for the Hydrological Cycle on Mars,milarly life may have been present in ice-covered lakes and permafrost springs on Mars. Evidence for past life on Mars may therefore be preserved in the sediments and mineral precipitates associated with these features.

11 Impact Craters, Water and Microbial Life,resent. We discuss some examples of microbial communities in terrestrial impact structures that are associated with some of these mechanisms of water enhancement and we discuss the importance of impact structures as places suitable for microbial life on other rocky planets, specifically Mars.
