McLaughlin, an American astronomer (1901-1965).〔 name="IAU-20101117" 〕 〔http://planetarynames.wr.usgs.gov/〕 The Mars Reconnaissance Orbiter has found evidence that the water came from beneath the surface between 3.7 billion and 4 billion years ago and remained long enough to make carbonate-related clay minerals found in layers. 〔 〔http://www.jpl.nasa.gov/news/news.php?release=2013-028〕 McLaughlin Crater, one of the deepest craters on Mars, contains Mg-Fe clays and carbonates that probably formed in a groundwater-fed alkaline lake. This type of lake could have had a massive biosphere of microscopic organisms.〔Michalski,J., J. Cuadros, P. Niles, J.
