    Summit of the Simba volcano (19,400 ft) – The summit crater lake is shallow and its water column completely transparent. The red color of the lake is from an algae that has developed special pigments in response to extreme levels of short wavelength (UVA and UVB) radiation.

    From October through November 2016, Nathalie Cabrol, director of the Carl Sagan Center at the SETI Institute, with members of the NASA Astrobiology Institute team based at SETI, went on a month-long expedition to Chile, visiting Mars-analogue sites between 800 and 6,000 km above sea level to collect samples and test in situ instruments in preparation for the Mars 2020 and ExoMars science payloads.

    Photos and posts from the field sites written by Nathalie Cabrol are available at the SETI institute website, and are linked to below.
